Networking security
Network administration measures to ensure data integrity include: maintaining
current authorization levels for all users, documenting system administration
procedures, parameters, and maintenance activities, and creating disaster
recovery plans for breeches, losses and virus attacks.
About Network Security
Data and network security must be maintained so that information can
only be accessed or modified by those authorized to do so. In any well
run business, it is wise to construct a comprehensive security policy.
This consists of plans and procedures which are in a document that states
how a company will protect the company's physical and information technology
assets. A company's security policy may include an acceptable use policy,
a description of how the company plans to educate its employees about
protecting the company's assets, an explanation of how security measurements
will be carried out and enforced, and a procedure for evaluating the
effectiveness of the policy.
One Solution: Firewalls
A firewall is a set of related programs, located at a network gateway
server, that protects the resources of a private network from users
from other networks. Basically, a firewall, working closely with a router
program, examines each network packet to determine whether to forward
it toward its destination. A firewall also includes or works with a
proxy server that makes network requests on behalf of workstation users.
A firewall is often installed in a specially designated computer separate
from the rest of the network so that no incoming request can get directly
at private network resources.
Computer Viruses
A virus is a piece of programming code usually disguised as something
else that causes some unexpected and usually undesirable event. A virus
is often designed so that it is automatically spread to other computer
users. Viruses can be transmitted as attachments to an e-mail note,
as downloads, or be present on a diskette or CD. The source of the e-mail
note, downloaded file, or diskette you've received is often unaware
of the virus. Some viruses wreak their effect as soon as their code
is executed; other viruses lie dormant until circumstances cause their
code to be executed by the computer over the Internet.

Some viruses are
playful in intent and effect ("Happy Birthday!")
and some can be quite harmful, erasing data or causing your
computer's hard disk to require reformatting.
Generally, there are three main classes of viruses:
File infectors. Some file infector viruses attach
themselves to program files, usually selected .COM or .EXE
files. When the program is loaded, the virus is loaded as
well. Other file infector viruses arrive as wholly-contained
programs or scripts sent as an attachment to an e-mail note.
System or boot-record infectors. These viruses
infect executable code found in certain system areas on
a disk. They attach to the Master Boot Record on hard disks.
Macro viruses. These are among the most common
viruses, and they tend to do the least damage. Macro viruses
infect your Microsoft Word application and typically insert
unwanted words or phrases.
The best protection against a virus is to know the origin
of each program or file you load into your computer or open
from your e-mail program. Since this is difficult, you can
buy anti-virus software that can screen e-mail attachments
and also check all of your files periodically and remove
any viruses that are found. |
