Worms and Trojans can make their way into local intranets fast if you don’t have a good firewall to protect your networking environment. Most of it originates from overlooked files like granting access to the Internet for specified users. But rest assured, unless you document and orient these people on potential risks, chances are the ones to whom you grant access will be the bane of your network security issues.
A worm can multiply fast if not contained immediately. For one, it can affect the whole network. So how do you go about it?
1. Unplug all the computers from the network. Cable disconnection would be a good start. If they are not connected, then there is no place for them to go. Depending on the number of workstations, you may have your work cut out for you. But at least it defeats the need to come and go from one workstation to the other once one is cleaned.
2. Scan the computers manually using a CD. As much as possible use a write-once optical disc. This way, if you find the worm or virus, you have it cornered. There is no place to hide nor go for them.
3. Restart and make a second check. Make sure everything is clean for one workstation. Do this for the rest of the computers that have been potentially affected.
This process requires a lot of patience. But it beats having to turn to the usual formatting and clean everything from scratch. It is indeed demoralizing, but the thing is, you just have to deal with it since better security policies need to be enforced on your end as far as users are concerned.

One click is all it takes to be infected and for the avid PC user, it would be wise to make sure that you look before you click. Malware issues can come in different forms like:
1. Emails
2. Popups
3. Links via Instant Messaging
In fact, even if you know the person who sent you the link, you cannot entirely rely on your relationship and trust with them as the main reason for clicking on the link. This was done before but today, people have to be aware that there are some accounts that can be easily hacked or even impersonated.
Much of these issues have plagued us through the years. Some have had their share of problems dealing with Malware and Trojans. They are different from viruses but sometimes, they can do more harm compared to the traditional viruses.
Even having anti-virus or anti-spyware protection is not guarantee from being contaminated with them. Remember, a click is all that it takes and all hell will break loose. For most, it is easy to remedy since they can reformat their computer. But think about the files you may lose from the moment you click on these links.
It may be hard to save these files since chances are they have already been infected. With that said, your files and PC are practically good as dead. So the moral of the lesson is, don’t be trigger happy with clicking. You are just raisin the stakes of being infected by doing so.

For most companies, the computer room where the company servers containing the delicate data originating from daily transactions is the most important place in the office. So while the people here are trying to figure out ways to safeguard these servers, it would be likewise important to consider external security measures such as placing locks and monitoring the activities with the use of spy cams.
Why is this important? The right question should be geared on how well do you trust you IT personnel. Evaluate their personality and see the extent to which they may betray the company and place operations in jeopardy. This not of course to discredit them but in reality, a lot of people use their knowledge and access as leverage towards being able to command salaries and money-related deals that many of us know as blackmail.
Also, physical intrusion is always a possibility. No matter how secure your area would be, it can be breached at anytime if you do not address the right measure to make it harder for them to gain access to the computer room. In short, the harder it is to get in to you computer room, the better it is. This only means you have prepared on the physical aspect of securing your IT area which is a good approach the sake of safeguarding hardware and data.

We know for a fact that the battle towards malicious software and viruses released on the web has caused a lot of pain as far as pinpointing and remedying them but apparently nothing has been done to really resolve them. We buy licensed software but we have to ask ourselves on the extent of their coverage. Are they up to date and can they really save us from all these uncertainties of getting online?
Microsoft has been a prime target, being one of the widely used operating systems we know of today. But while Bill Gates and company are doing their part in being able to address the various intrusions and headaches that they can do with a simple click, you just don’t know who to trust these days. Even the software companies have the ability to manipulate and do some foul work and they are occurring right under our very noses.
Security researchers concede that their efforts are largely an exercise in a game of whack-a-mole because botnets that distribute malware like worms, the programs that can move from computer to computer, are still relatively invisible to commercial antivirus software.
So with all these things set on the table, is the cyber world safe for anyone? We can fend off threats but the question is are we resolving the situation or merely providing a temporary solution to the problem? Sad to say, it is the latter. We are content with detecting them but it is really the cleaning and protection part that needs improvement.

If you are in charge of network security, one thing you may want to consider as far as laying down the law in safeguarding your network is the regular change of user passwords to avoid potential hackers and cracks based on how their passwords can be easily guessed.
For some users, it is easy to figure out their passwords. The normal passwords that people use include:
1. Birthdays
2. Anniversaries
3. Car Plate Numbers
4. Mobile Phone Numbers
5. Adding 123 to their names, or
6. Using “PASSWORD” as their password
Now there will be a lot of potential combinations depending on the length of the password. That is why the longer passwords (8 alphanumeric characters) are encouraged for users who access the network.
But while the probabilities of guessing or cracking passwords offer a lot possibilities, employing a regular maintenance as far as changing them is indeed something ideal to combat these hackers or malicious people from gaining access to the network and the programs in use.
Once cannot avoid the fact that some people’s curiosity and call for fame are the main reasons for wanting to be a hacker or code cracker. It is evident in people who are looking to try out their skill. They don’t think of the outcome which can cause a lot of problems.
So one good tip to avoid being hacked is to think like one. Once you do, think of security policies that can make it hard for you to breach a system. That is the best way to stay efficient in your line of duty in any organization.
