Personal Cyber Security - TEEX's Holiday Guide, Part 2

Earlier this week we blogged about the importance of personal cyber security, and how poor practices can endanger personal and company data. In this blog, we’ll address several important items that everyday users encounter and how to secure them.

Anti-Virus Software - Without proper virus protection, your PC may have a Trojan Horse virus quietly waiting to carry out a malicious attack, using your computer and Internet connection.

If you have a personal computer running any version of Windows, you must have up-to-date antivirus software. Fortunately, there are many options available, at costs ranging from free to $200 per year. A new PC will generally come with a trial version of Norton or McAfee antivirus, lasting from 90-days to one year. During the program set-up, pay attention to the automatic updates and scheduled scan settings. Both must work for full protection. Make sure the scheduled scan is during a time when the computer is on and idle. Watch for the automatic updates to occur, usually once per week.

Free antivirus software, such as AVG, protects millions of users daily. Educate yourself by checking reviews on the Internet and use the software you are most comfortable with. Bigger and more expensive isn’t always better, as more layers of protection sometimes slow computers down noticeably. The important note is to use antivirus software of some kind and keep it up to date!

For everyone running iOs (on all Apple products) and Android (on other smart devices), it’s time to accept that your devices are susceptible to the same security problems as Windows pc’s. Install antivirus now so you won’t be the first in your office with problems.

Another thing to be cautious of is using mobile wireless networks in public places with your smartphone. More and more people use their smartphones to access Facebook, twitter, personal emails, and bank accounts. Most smartphones are set up to automatically switch to open access wi-fi accounts when they are available. This leaves the information on your smartphone available to any hacker who sets up a wi-fi hotspot in a public location. To save yourself the possible exposure, turn off the wi-fi on your phone and stick to using the phone's own data plans to gain internet access.

Passwords - Without proper password security, your entire online presence: facebook, movies, and bank accounts can be hacked, hijacked, and erased.

The use of personal passwords seem to have the greatest difference between expectation and reality. In an IT security analyst’s perfect world, each of your passwords would consist of at least ten random letters, numbers and special characters. Each account or device would have a different password and they would change at least every ninety days. Unfortunately, the most popular password in use today is 12345 or password.

Although impractical, we should never use the same password on more than one account. TEEX System Security Analyst Tyler Burwitz has some realistic suggestions for that problem.

Consider three or four primary passwords, each with a different level of security.
  • A long, complex password, limited to high-security financial accounts.
  • A different, secure password for other important accounts.
  • A password for less important accounts.
  • A “throw away” password, for when you just have to sign up for something.

By using these methods, your bank account can’t get hacked along with your twitter account.

Burwitz offers these suggestions to help you choose more secure passwords.
  • If the word or phrase is on your facebook page or any other online presence, don’t use it, even with variations. Good examples are pets, places and names.
  • If it is in the dictionary, don’t use it, even with variations.
  • Think PassPhrase instead. It doesn’t have to be a word.
  • Longer is better. A 20-character lower-case password is better than a 10-character complex password.
  • Use spaces in the password, if allowed.

Once a hacker has a possible password for you, he has programs available that run all the possible variations of the word. If he knows your first pet was named Fido, the program will try Fido1, 1Fido, etc.

One level more secure than a long, complex password is two-step authentication. When a user attempts to log into an account using two-step authentication, the server sends a one-time text code to the users cell phone, which is then entered on the login screen. Even Wired reporter Matt Honan wrote recently how he was hacked and his life erased, even though he was using two-step authentication. According to Burwitz, “If someone has the time and patience, they will figure out how to get your data from you. It's not as hard as you think, usually taking an hour or less.”

Biometrics, such as a fingerprint or iris scan, are beginning to play a greater role in security, but as a second layer of authentication instead of replacing passwords.

Some password security procedures are being reconsidered. For example, is it better to have a poor password changed every 90 days, or a long, complex password that is only changed annually?

Complaints usually accompany mandatory password changes. Burwitz explains those requirements several ways. “First, we have to follow the law. Information Technology Security must maintain a high level. We also must prevent loss of data that can result in financial loss for the agency, as well as damage to our reputation, and in an extreme case, possible personal harm.”

Game Consoles - Many of the latest game consoles have access to the Internet through a home’s wireless router, allowing users to play games with other users worldwide. It’s important that parents understand how this works and take security measures that range from disabling the “live” account to ensuring the users screen name doesn’t divulge personal information. Even though the security settings have been modified to prevent live play with strangers, other players may have different settings allowing unknown persons into the game. Parents should visit the manufacturer’s website to fully understand the capabilities of the game console before giving it access to the Internet.

Wireless Routers - Operating an unsecure wireless router at your home or business leaves you open to compete data loss and responsibility for everything that occurs on your Internet connection. These routers allow our favorite devices to connect to the Internet, as well as share information among themselves. Unfortunately, most routers are shipped with even basic encryption disabled, allowing an outsider to do several nasty things, from slowing Internet speeds by using bandwidth to stealing your files and data.

In the past, setting the highest level of security possible for your wireless router was difficult and frustrating. The latest routers use a push-button method to connect devices, while older routers still require passwords. If you are having difficulty, consult the setup instructions that came with the router or the manufacturer’s website. You can also search YouTube for “connecting to the (insert router model here) router” or a similar phrase. Finally, Burwitz suggests, “Call a family member who knows what they're doing, probably your 15-year-old son or grandson. Also, some companies allow IT personnel to help you in this type of situation.” The important message is to get help to secure the router.

In 2013 and beyond, we must approach personal online security with the same emphasis as locking our home or car and caring for our purses and wallets. We must also be mindful that our poor security habits can compromise other computers or networks. Please take the time to have a safe, secure Internet experience this holiday.

Personal Cyber Security - TEEX's Holiday Guide, Part 1

Christmas is only days away, and with it, the deployment of millions of new Internet devices into the happy hands of young and old. Most of these computers, smart phones, tablets, game consoles, and routers are shipped without any security in place. Personal computers normally come with some type of antivirus installed for a trial period that must be renewed for continued protection.

As more of our personal lives and business live on the Internet, cyber security is moving to the forefront. Education and awareness about the kind of security you need are essential. Some company's advertisements would want you to believe that you are in extreme danger and that their paid monitoring services are essential for cyber survival. Driven by extreme examples, some casual Internet users even feel it necessary to physically disconnect their PC from both the Internet and electrical system. Others may decide against using webcams and communications software for fear that it could be used to spy on them.
On the other hand, Internet security is ignored by many until something "happens." Consequences can range from "someone saying bad things about you on twitter," to losing, at least temporarily, your money, history, ... everything.

To raise awareness and address the growing threat, TEEX’s Knowledge Engineering division, along with the Department of Homeland Security (DHS) and the Federal Emergency Management Agency, offer several online cyber security courses. This DHS/FEMA Certified Cyber-Security Training is designed to ensure that the privacy, reliability, and integrity of the information systems that power our global economy remain intact and secure. The 10 courses are offered through three discipline-specific tracks, targeting everyday non-technical computer users, technical IT professionals, and business managers and professionals. These courses are offered at no cost, and students earn a DHS/FEMA Certificate of completion along with Continuing Education Units (CEU) at the completion of each course.

According to Michael Sevier, an instructor with the program, a cyber-security threat may have unforeseen consequences. For example, a cyber attack on a community hospital may have far-reaching repercussions. Unable to operate without electronic medical records, the attack could cause the complete evacuation of the facility, even though it’s a beautiful day and everything else is functioning. The evacuation may tax the resources of the the community's police and fire departments as well as transportation systems and medical facilities. According to Sevier, “Everything is connected on some level, and our goal is to make emergency planners, first responders and entities such as hospitals, power plants and other essential services aware of the threat so that they can prepare and plan.”

Poor personal cyber security can be a threat to large organizations. For example, connecting a work computer which has access to company data on servers, through an insecure wireless network at home or at a local coffee shop, can endanger company data.

To help you ensure your personal devices and home networks are secure this holiday season, our next blog will cover basic personal cyber-security essentials, such as antivirus software for PC’s, how to realistically create and use a secure password, the essentials for game console security and how to make sure your neighbor isn’t piggybacking on your new wireless home router.

In the meantime, check out TEEX’s Cyber Security course offerings. They are free and designed for everyday non-technical computer users, technical IT professionals, and business managers and professionals.

Preventing the Next Pandemic: Training a bio-manufacturing workforce

Blockbuster Hollywood films such as “Contagion” and “Outbreak” have dramatized mass-casualty disease outbreaks and the ensuing panic as scientists search for a vaccine or cure. In the movies, the main characters find a way to develop and manufacture a vaccine just in time to save the population. But in reality, it can take months or even years to develop and manufacture a new vaccine. And the U.S. has little infrastructure set up for rapid development and manufacture of biopharmaceuticals and vaccines.


But The Texas A&M University System is leading the way toward enhancing the nation’s abilities to counter biological and pandemic threats with vaccine manufacturing in the United States. The A&M System was selected as a U.S.Department of Health and Human Services Center for Innovation in Advanced Development & Manufacturing to bolster the nation’s emergency preparedness by providing surge capacity for vaccines and medical countermeasures to chemical and biological events.

As an education partner in the new center, the Texas A&M Engineering Extension Service (TEEX) will play a major role in developing the workforce of skilled technicians who will help bring life-saving therapies to market as the infrastructure for biopharmaceutical manufacturing is built in Texas.

TEEX is partnering with the Texas A&M Engineering Experiment Station, Texas A&M College of Engineering, Blinn College and Baylor College of Medicine to train the workers needed for the new bio-manufacturing industry.

We have already developed five courses for operators and technicians, and we will be adding even more targeted training. The manufacturing workforce needed for this industry will require skills in good manufacturing practices, processing protocols, clean room techniques, safety, and quality assurance. The National Center for Therapeutics Manufacturing at Texas A&M University will provide student access to wet labs and equipment such as bioreactors and centrifuges as well as other bio-manufacturing devices needed to prepare them for this new career.


Although this is a new training program, TEEX has a long history of expertise in working with manufacturers on improving productivity and implementing lean manufacturing as well as clean-room techniques and product development.   

The first TEEX courses in therapeutics manufacturing will be offered in conjunction with Blinn College in the Fall of 2013. Through our articulation agreement with Blinn College, students who complete these courses will be eligible for a one-year certificate program or two-year Associate of Applied Science degree in therapeutics manufacturing. The Blinn certificate and associate’s degree programs were recently approved by the Texas Higher Education Coordinating Board and the Southern Association of Colleges and Schools.

We're very excited about how we can help improve the nation’s emergency preparedness for infectious diseases and chemical, biological, radiological, nuclear and explosive threats.  This dovetails with our other homeland security and emergency preparedness training programs, and has great potential benefits for all citizens.

Fire Extinguishers: Are you prepared?

Do your kids know two ways out of every room?  Have you practiced your family’s fire emergency escape plan? October is Fire Prevention Month, and the National Fire Prevention Association(NFPA) also sponsors “FirePrevention Week”  from October 7-13, with special emphasis on educating families and children on fire safety.

Along with working smoke detectors and an emergency plan, having a portable fire extinguisher in your home can save lives and property by putting out small fires or containing one until the fire department arrives. But portable extinguishers have limitations. Because fire grows and spreads so rapidly, the No. 1 priority for residents is to get out safely. Make sure everyone in the family knows how to get out quickly, where to meet outside, and how to call 911.
Remember three things when purchasing and using a fire extinguisher: Make Smart Decisions. Get Training. Maintain Your Extinguisher.

Make Smart Decisions
Use a portable fire extinguisher only when:
  • The fire is confined to a small area, such as a wastebasket, and is not growing;
  • Everyone has exited the building; 
  • The fire department has been called or is being called;
  • The room is not filled with smoke; and
  • Your instincts tell you that it is safe to use an extinguisher.
Know when to go. Fire extinguishers are one element of a fire response plan, but the primary element is safe escape. Every household should have a home fire escape plan and working smoke alarms.

Get Training
Get the right kind of extinguisher. For the home, select a multi-purpose extinguisher (can be used on all types of home fires) that is large enough to put out a small fire, but not so heavy as to be difficult to handle. Check this page for more information on the different types of extinguishers.

Choose a fire extinguisher that carries the label of an independent testing laboratory. Read the instructions that come with the fire extinguisher and become familiar with its parts and operation before a fire breaks out. Local fire departments or fire equipment distributors often offer hands-on fire extinguisher training.

To operate a fire extinguisher, remember the word PASS:
  • Pull the pin. Hold the extinguisher with the nozzle pointing away from you, and release the locking mechanism.
  • Aim low. Point the extinguisher at the base of the fire.
  • Squeeze the lever slowly and evenly.
  • Sweep the nozzle from side-to-side.

Watch this great video that demonstrates the technique.









Mount or install fire extinguishers close to an exit and keep your back toward a clear exit when you use the device, so you can make an easy escape if the fire cannot be controlled. If the room fills with smoke, leave immediately. Even if you think you have doused the fire, don’t cancel your emergency call.  Let the firefighters decide if the fire is really out.
Maintain Your Extinguisher
Fire extinguishers need to be regularly inspected and checked to ensure that:
  • They aren’t blocked by furniture, doorways, or anything that might limit access in an emergency.
  • The pressure is at the recommended level.
  • All parts are operable.
  • The outside of the extinguisher is clean. Clean off any oil or grease that might accumulate.
  • Shake dry chemical extinguishers once a month to prevent the powder from settling or packing. Check the manufacturer's recommendations.
  • Pressure-test the extinguisher to ensure that the cylinder is safe to use. Check the owner's manual, the label, or the manufacturer to know when to test.
  • Immediately replace the extinguisher if it needs recharging or is damaged in any way. 
Having working smoke alarms, fire extinguishers, and an emergency plan is vital. Possessions can be replaced—but you can’t. Visit TEEX’s FirePrevention page for more fire safety information, plans, and tips.

A Key Element of Preparedness: Self-Reliance


September marks National Preparedness Month, and it's a great time for you and your family to review preparedness plans and update emergency kits. Does your business, organization, church or school have an emergency plan? Find out! Many resources are available to help you become prepared and self-reliant in case of a disaster. Reach out to emergency response and preparedness groups in your community for advice or assistance, and participate in events that educate your community about preparedness.

1. Learn about emergency hazards & the appropriate responses
2. Make a communications plan  
3. Build an emergency kit 
All disasters are inherently local. They affect families and their communities, businesses and their customers, and organizations and their members. It takes all aspects of a community – not just the government – to effectively prepare, respond, and recover from emergencies and disasters. Building community resilience requires close coordination between the government, community organizations, individuals, and emergency managers to plan for the needs of the whole community.
However, the most important thing you can do as an individual is to be self-reliant during disasters
Peparedness is an individual responsibility. If you are prepared, it frees up valuable resources and allows our first responders to assist those who are in the greatest need. Self-reliance also extends to helping neighbors and friends around you who may need help before emergency responders can arrive. 
Start preparing now

It is important to prepare now. Families may not be together when an emergency happens and you may not have access to cell phones, gas stations, banks, grocery stores or some of the other things that you are used to having every day. Be informed. Make a plan. Build a kit. Get involved.

Preparedness kits are needed in multiple locations like your home, cars, and at your workplaces



Disasters can happen at any time, so it is important to be prepared at places where you spend large amounts of time, including your home, your office, and your car.


Important Links for Staying Informed, Making a Plan, Building a Kit, and Getting Involved

Your involvement is crucial in being prepared and taking care of yourself and your family. It also plays a vital role in helping your community react, respond, and recover from emergencies and disasters. Remember to make a plan, get a kit, and stay informed!

Passenger Rail Rescue course offered at Disaster City®


In 2011, a passenger train with 200 people onboard crashed into a tractor-trailer near Reno, killing five. Sixteen people were injured when two passenger trains collided in Oakland. And a train carrying more than 175 passengers from California to Chicago derailed in Nebraska, injuring nine.
For emergency responders with passenger rail service running through their communities, a train derailment or accident is a nightmare. And until recently, little training was available to help responders prepare for such an incident.

So when Fire Chief Dan Small of Cumberland, Maine, called the Texas A&M Engineering Extension Service (TEEX) to ask for specialized rescue training for rail emergencies, the wheels started turning. With its subject matter experts in fire and rescue and a seven-car Amtrak passenger train derailment at TEEX’s renowned disaster training facility, Disaster City®, a passenger rail rescue course was a natural fit.

TEEX reached out to Amtrak, who had donated the locomotive and coaches to the training organization in the 1990s. Amtrak collaborated with TEEX on developing a course designed to provide responders with the knowledge, skills and abilities to perform search and rescue operations at a passenger train or commuter train disaster. A guest instructor from Amtrak came to College Station to assist with the delivery of the Passenger Rail Rescue class in December 2011 and April 2012.  An Amtrak instructor will again be on hand for the September 2012 class, where students will learn first-hand about the challenges and hazards of each specific type of Amtrak passenger rail car.

TEEX’s hands-on course uses the seven-car passenger train derailment at Disaster City® as well as some specialty props that allow students to learn specific skills such as “hot-cutting” through metal and how to remove an Amtrak emergency access window in 15 to 20 seconds. They also practice extricating victims through windows and doors, especially from cars that are turned on their sides or at a precarious angle on top of an adjacent car.   

Course participants also have homework: they read and discuss case studies and NTSB reports of previous rail incidents that tie into the hands-on scenarios they face during the class. One of the instructors is Brian Freeman, who spent 30 years on the London Fire Brigade. He provides his unique perspective on responding to the London Underground bombings on July 7, 2005, and discusses techniques for dealing with train accidents inside tunnels.

video

The 40-hour Passenger Rail Course concludes with a realistic 4-hour nighttime train derailment disaster exercise involving many volunteer “victims” from the local community. The exercise includes difficult access challenges for the students to overcome, such as people trapped deep inside the train. The students’ mission is to rescue as many “victims” as they can as fast as they can. 
Besides Cumberland, Maine, responders from New York City, Boston and Fort Worth have completed the course so far.

 With more than 220,000 miles of track in the United States, and more than 8,800 passenger locomotives and coaches, safety and emergency preparedness are vital. This course is one step toward making sure those who respond to a rail disaster in their community have the training and skills to save lives.

Guest Instructors at Texas Fire Schools make the difference.

The brotherhood of firefighters crosses borders and generations. Nowhere is this more evident than at the Texas Fire Training Schools, held each year at the Brayton Fire Training Field in College Station, Texas, and conducted by the Texas Engineering Extension Service (TEEX).

The schools began in 1930 when 196 firefighters gathered in College Station, near Texas A&M University, for the first Texas Municipal Fire School (watch this year's video). Other specialized firefighting schools followed. The Industrial Fire Training School, now in its 50th year, draws members of industrial emergency response brigades and safety officers from global oil & gas and chemical companies. The annual Spanish Fire Training School (Escuela para Bomberos en Español) is the largest fire school anywhere for Spanish-speaking firefighters.

These world-renowned schools have earned their reputation in large measure through the generations of firefighters who have attended the schools and taken what they have learned back to their home communities. Volunteer guest instructors play an integral part in the equation. These Fire Training Schools would not be possible without the dedication of the guest instructors and safety officers who come each year to share their knowledge with the next generation of firefighters.

They volunteer their time and expertise to make sure every firefighter who leaves is well-prepared and ready to respond when the alarm sounds – whether they live across the state or across the world. This year, TEEX honored two of these guest instructors who have served the Texas Fire Schools and the fire service for 50 years or more.

Chief Salvador Lambretón Narro was named Chief Instructor Emeritus and recognized for 57 years of leadership, vision, dedication and support to the Texas Fire Training School (shown at right in maroon shirt). The retired Fire Chief from Monterrey, Mexico, was honored on the opening day of the Escuela para Bomberos en Español. Chief Lambretón began his firefighting career in 1947 and first attended the Municipal Fire Training School in 1950. He collaborated with Fire School Chief Emeritus Henry D. Smith to establish a professional fire training school for Latin American firefighters, which has expanded to attract Spanish-speaking “bomberos” from 17 countries. See the KBTX story on this year's Spanish School.

Chief Ernest Patschke was also recognized during the Municipal Fire Training School for his 50 years of service to the school as a volunteer guest instructor in pump and ground-cover operations. Patschke joined the Thorndale Volunteer Fire Department in 1951, and rose to Fire Chief. He attended his first Municipal Fire School in 1952 and became a guest instructor at the annual school in 1962, where he says students inevitably take away knowledge “they didn’t know they didn’t know” and can take that knowledge back to protect the citizens in their hometowns. Watch TEEX's Lee Hall awarding Chief Patschke in the KBTX video and read the Bryan-College Station Eagle article.

THANK YOU, Chief Lambretón, Chief Patschke, and all of the guest instructors and safety officers who give of their time and experience to benefit firefighters from all over the world. We couldn’t do it without you!


Los instructores invitados contribuyen a las
Escuelas para Bomberos de TEEX.




La hermandad que existe entre bomberos trasciende fronteras y generaciones. Nunca está más evidente esta gran fraternidad que en la Escuela de TEEX que se organiza todos los años en el Campo Brayton de Capacitación para Bomberos en College Station, Texas.





Los orígenes de la Escuela se remontan al año 1930 cuando se juntaron 196 bomberos en College Station, cerca de la Universidad de Texas A&M, para asistir a la primera Escuela para Bomberos Municipales (2012 video). Con el tiempo se fueron organizando otras escuelas especializadas para bomberos. La Escuela Industrial, que acaba de cumplir 50 años, es la meta anual para bomberos y profesionales de seguridad de empresas petroleras y químicas de todo el mundo. Y no hay escuela para respondedores hispanohablantes más grande que la Escuela para Bomberos de TEEX.  

Estas escuelas de renombre mundial se han ganado su fama en gran medida gracias a las generaciones de bomberos que han venido a capacitarse en College Station para luego servir de multiplicadores en sus comunidades locales. Los instructores voluntarios tienen un papel integral en este fenómeno. La Escuela no sería posible sin la dedicación de los instructores invitados y oficiales de seguridad que vienen todos los años para compartir sus conocimientos y su experiencia con las nuevas generaciones de bomberos latinoamericanos. 

Vienen como voluntarios a la Escuela para ayudar a preparar a los participantes para que estén bien capacitados y listos para responder cuando suene la alarma dondequiera que sirvan como bomberos. Este año, TEEX homenajeó a dos instructores que han servido a las Escuelas y al servicio de combate de incendio por más de 50 años.

Como parte de la ceremonia de inauguración de la Escuela de este año, el Jefe Salvador Lambretón Narro fue nombrado Jefe Instructor Emérito y fue reconocido en consideración a su liderazgo, visión y apoyo durante sus 57 años de dedicación a la Escuela. El Jefe Lambretón, de Monterrey, México, inició su carrera en los servicios de combate de incendio en 1947. Al poco tiempo, en 1950, asistió por primera vez a la Escuela para bomberos en College Station, que en aquella época era la Escuela Municipal. Desde entonces, consciente de la gran necesidad de brindarles una
formación profesional a los bomberos latinoamericanos se entregó, en estrecha colaboración con el Jefe Emérito y Director de la Escuela Henry Smith, a la creación de lo que es hoy la Escuela para Bomberos en Español a la que asisten participantes procedentes de 17 países.
Nota periodística en inglés.  

Durante el curso de la Escuela Municipal del corriente, TEEX también reconoció al Jefe Ernest Patschke por sus 50 años como instructor voluntario en los cursos de operaciones de bomba e incendio en superficies. Patschke se incorporó al Departamento de Bomberos Voluntarios de Thorndale en 1951, para ascender eventualmente al puesto de Jefe. Asistió por primera vez a la Escuela Municipal en 1952 y fue nombrado instructor invitado en 1962. Según el Jefe Patschke, los alumnos se llevan de la Escuela conocimientos “que no sabían que no sabían” para proteger a los vecinos de sus comunidades. Ver video KBTX  y nota en el periódico Bryan-College Station.

GRACIAS al Jefe Lambretón y al Jefe Patschke, y a todos los instructores y oficiales de seguridad que se ofrecen como voluntarios para beneficio de los bomberos de todo el mundo. Si no fuera por ustedes no podríamos cumplir con nuestra misión.
