Security Strategy

IT Security strategy is similar to Military strategy, which involves implementing different defense mechanisms in different layers so that if one mechanism fails, next might stop as an attack from progressing further. Network Security Solutions includes a firewall, web filters, intrusion detection & prevention for packet filtering, stateful packet inspection and threat detection on the basis of traffic behavior. Endpoint protection solutions include anti-malware, personal firewall, enterprise mobility management and solutions to detect anomalous activities on endpoints. Data is very important for any corporate, hence data and application security solutions are usually deployed on critical data. The alerts generated by Network Security Solutions, Endpoint Security Solutions and Data Security Solutions are collected at Security Operations Centre and further security teams do the forensic analysis to understand the attack progression and initiate incident response system. Excess amounts of logs and false-positive alerts are considered as “noise” and security teams need to identify and prioritize the handling of incidents, which are a real risk to businesses. It is humanly impossible to analyze the massive log data, hence the concept of machine learning is used to effectively and efficiently log data analyzing. Machine learning is playing an increasingly important role in the security domain, mostly for identifying known threats. However Attackers do bypass the preventive controls by new delivery methods, hence such new threat data do require human expertise. Once detected, the attack needs to be contained to prevent spreading and further doing damage. Threat containment can be automated in a few cases but mostly it also requires human action of the basis of expert analysis. Regulatory compliances and good security practices help from any threat and increasing the security of the network.

The increasing uses of Mobile devices & Cloud applications have given more opportunities for attackers to intrude into corporate networks. There is no doubt that Cyber Attackers have outpaced the Security preparations of the Corporate World. Many times Attackers get success in bypassing security perimeter controls, enter the network and remain undetected and exploit the confidential data. It is time for every Corporate to improve the IT security strategy and get a step ahead of Attackers.
