In the ever expanding cyber world, threats loom large and protecting unsuspecting netizens from the terror unleashed by unscrupulous elements such as Viruses, Trojans and Malware is a need of the hour. But then taking everything into consideration safeguarding the interests of PC users from the last of the evil trio ie Malware is something which needs to be done out on a priority basis. One of those facets on which a company tends to work hard through its comprehensive security support packages.
Understanding Malware and its repercussions:
Ask the techies and they would tell you that malware is a rogue program utilized by attackers to infiltrate network and system defenses, disrupt business operations and funnel sensitive data out of corporate and personal computers. Unfortunately, there is no single-step fix to thwart the same and even detect infections. In short, stopping malware in its tracks requires an approach grounded in awareness and control.
How to stop malware from breaching the defenses?
According to security support professionals, malware such as bots and spyware often go unnoticed for far too long. Further, well-crafted malware can not be detected by antivirus software and intrusion detection systems. So, in such a scenario the first line of defense against such a formidable foe is to get acquainted with the IT infrastructure and monitor it round-the-clock for detecting anomalies. A task which one can undertake by taking steps such as:
• Central Management of Logs
Systems and network devices across the enterprise are subject to anomalous activities. And even an operational incident say for instance a surge in CPU load on a server could end up having serious security implications. Further, even the slightest degree of increased load can be anything but attributed to the presence of malware on a system.
• Deploying sensors
Intrusion detection and host-based sensors on key servers at pivotal points on the network can be extremely beneficial. However, maintenance of host intrusion detection systems (IDS) tends to be more burdensome than managing network IDS. Moreover, even though traditional IDS may not block infections but it may eventually end up offering additional visibility into the environment.
• Constant Monitoring
Monitoring of outbound network traffic can be an ideal way for detecting infected systems seeking instructions or trying to leak data to their masters. One can even up designing a network IDS sensor for scrutinizing outbound traffic or employing traditional network monitoring tools for the same purpose.
• Detecting abnormalities
Any unauthorized changes to the state of the systems can often be caused by a malware resident on the system. Better still as the case would while some malware ends up residing purely in the memory of the infected system a majority of infections can end up leaving their footprints on the file system or registry. Some of the host IDS can end up detecting such changes to the system's integrity.
The above mentioned points can actually come in good towards taking care of any security related lacunae residing on a system. However, if one still feels taking security of the IT network is not within their ambit then PCCare247 with its extensive portfolio of security support packages would be more than happy to lend a helping hand.
