The UAB Electronic Phonebook is indeed "user centric." Advantages of this approach include:
- Users are free to change their own passwords, preferred e-mail server, and some other information.
- UAB Electronic Phonebook listings come directly from official Human Resources (ORACLE) and Student (BANNER) databases, and are updated daily. As "official" records, they serve as the basis for present and future services which will make use of the same user name (also referred to as BlazerID) and password. As e-mail administrator, you should encourage users to know about this service, select their own BlazerID, and keep up with their own password.
Computer viruses implant instructions in other programs or storage devices and can attack, scramble, or erase computer data. The danger of computer viruses lies in their ability to replicate themselves and spread from system to system. Few computing systems are immune to infection.
The following activities are among the most common ways of getting computer viruses. Minimizing the frequency of these activities will reduce your risk of getting a computer virus:
- Freely sharing computer program and system disks, or downloading files and software through file-sharing applications such as BitTorrent, eDonkey, and KaZaA
- Clicking links in instant messages (IM) that have no context or have only general text (even from someone you think that you know)
- Downloading executable software from public access bulletin boards or websites
- Using your personal disk space with public computers that are used by more than one person
- Opening email attachments from people you don't know or without first scanning them for viruses
- Opening any email attachment that ends in .exe, .vbs, or .lnk
- Continually running your machine without the appropriate patches
Signs of a Virus Infection
If your computer begins to act strangely, or if it stops being able to do things it has always done in the past, it may be infected with a virus.
Symptoms such as longer-than-normal program load times, unpredictable program behavior, inexplicable changes in file sizes, inability to boot, strange graphics appearing on your screen, or unusual sound may indicate that a virus is on your system.
However, it is important to distinguish between virus symptoms and those that come from corrupted system files, which can look very similar. Rule out more standard causes before suspecting a virus.
How to Avoid Computer Viruses
The following are some recommendations for safe computing:
- The most important thing you can do to keep your computer safe is to install virus detection software and keep the virus patterns up to date. Antivirus programs perform two general functions: scanning for and removing viruses in files on disks, and monitoring the operation of your computer for virus-like activity (either known actions of specific viruses or general suspicious activity). Most antivirus packages contain routines that can perform each kind of task.
- Keep your operating system current with the latest patches and updates. The writers or viruses and worms often exploit bugs and security holes in operating systems and other computer software. Software manufacturers frequently release patches for such holes.
- Backup your files. Viruses are one more very good reason to back up your files. UAB employees can use UABFILE to store their data. UABFILE is kept in a secure location and backed up regularly.
- NOTE: If you back up a file that is already infected with a virus, you can re-infect your system by restoring files from backup copies. Check your backup files with virus scanning software before using them.
- Obtain public-domain software from reputable sources. Check newly downloaded software thoroughly using reputable virus detection software for any signs of infection before running the install programs (.exe, etc). This can also help protect you from Trojan horse programs.
- Quarantine infected systems. If you discover that a system is infected with a virus, immediately isolate it from other systems and report the incident. In other words, disconnect the system from any network and do not allow any of the machine's files to be moved to another system. Once the system has been disinfected you can copy or move the files.
- If you use a desktop version of MS Outlook, minimize use of the preview & reading pane options.
The first step in keeping your password secure is to create a good one. After you've created a strong password, continue with the suggestions below to keep it safe:
- Never share your password with anyone.
This includes family, friends, significant others, computer support people, and bosses. If you need someone to read your email, you can have that person do so without using your password by using the delegates feature in MS Outlook.
- Never save your password when prompted by your web browser or any other programs.
You can turn this option off in Internet Explorer (Tools -> Internet Options -> Content -> AutoComplete) & Mozilla (Tools -> Options -> Security).
- Change your password regularly.

- Make your password easy to remember, but hard to guess.
Use a lyric to a favorite song, for example:
"How much is that doggie in the window":
For more security, add a capital letter & convert an 'i' to a '1':
- Never send your password via email - even if the request looks official.
Any request to send your password via email is most likely a phishing attempt.
Faculty, staff and students who are involved in professional, academic, or student-social organizations are sometimes interested in hosting a web site for their group and want to use a domain name that does not end in uab.edu.
UAB cannot provide DNS (Domain Name) service for domains other than uab.edu. However, what we can do is register an on-campus server with a uab.edu name, and then you can arrange for an outside Internet Service Provider (ISP) to provide the name www.alabama_engineers.org and point it to your UAB server. The end result is that someone who types the URL www.alabama_engineers.org into their web browser will be taken to the organization's home page, which may happen to be sitting on a computer housed at UAB. Most ISP's charge a small fee for providing you with this service.
A domain name such as the one described above is called a third-level domain name. There is a $500 one-time fee for creating new third-level domains. There is no additional charge for registering names within the domain once it is set up. Third-level domain names should be requested by the department network contact.
"Strange network problems" can be caused by DUPLICATE IP ADDRESSES. If the workstation can send traffic off its segment to another subnet in our 138.26 class B address range but can not get to a location off campus, it is very possible that the workstation IP address has been incorrectly set to use the campus gateway (18.104.22.168) instead of its own address. Problems within your building network that affect only one or two machines can be caused by duplicate addresses, also.
One way to check for duplicate IP addresses is to look in the arp cache of the machine having problems. In Win 95/98 or NT, at the DOS prompt type the command "arp -a". For entry of 22.214.171.124 you should see a MAC address starting like 00-00-a2....
Because your BlazerID password is used to open the door to many services and features on the UAB network, it is vital that it be strong enough to resist guessing by casual means. Someone breaking into your UAB records can be the first step toward identity theft which is being well-publicized now. To be sure you have a strong password, make sure it follows these rules:
Every unit at UAB with devices connected to the UAB campus network should have a "network contact" person, even if there is no department server or local area network. At least one person within your department should be designated to be responsible for communicating your requests to DC/NS, and for assisting network users with basic configuration, software installation, computer training, and problem solving.
- Each department or unit at UAB should have an officially designated "network contact" person.
indicating who is to be considered the official contact person.
- Data Communications / Network Services (DC/NS) recommends that the contact person be a trained computer professional.
- If the "network contact" person is not a UAB employee, the department should additionally designate a contact person who is a UAB employee.
), and for security reasons these must originate from a server registered through DC/NS.
introducing the new person. If no replacement arrives before the old person departs, the last "network contact" should hand this function to their supervisor or other person in the department, who will then hand the job to the replacement person when they arrive. IP records, and any other records, should be turned in to the department for safekeeping.
- If the "network contact" left UAB without notifying DC/NS, the dean, director or department head should contact DC/NS with the name of the replacement contact person.
?subject=Request new IP numbers';
- Communicate network problems to DC/NS, and assist in trouble-shooting and problem resolution. Please call 4-3540 to report network communications problems, and call 4-7777 to report network wiring problems. You may also report problems via web interface.
- Coordinate equipment installation and relocation with DC/NS.
There are many wall jacks with data (network) ports installed throughout UAB buildings. Usually, the only ports that are active are those in use; other ports are de-activated. How can you tell?
What if suspect your network port has developed a problem of some sort?
To check whether the port has been activated and is working:
- Room Number
- Jack Number (it is written on the face plate)
- Port position number (If there are two DATA ports, the one on the left is D1 and the one on the right is D2. If there are four DATA ports, D1 is the upper left, D2 is upper right, D3 is lower left, D4 is lower right).
AskIT will check to determine if the port is activated and whether it appears to be working correctly. If the port shows as active but does not work correctly, either AskIT (or you) can dispatch a technician to fix it by calling 4-7777.
