It is evident that there has been a leaping increase in the technological advances, with the onset of IoT (internet of all things). This is well complemented by the advances in the cloud technology. However, with an increase in the technology level, there has been an increase in instance of security breach. Although there has been relentless effort in the R&D of the next generation antivirus solutions, organizations continue to be a target of ransomware and other malwares. The security breach continues to occur, due to the change in the threat matrix. Today, the area of corporate governance is not confined to one postal address; rather it has its end points to the farthest geographic landscape. With the addition of devices like laptops, tablets, and mobiles to the organizations core network, the need of `vigilantisms has increased many folds.
End Point Security solutions are aimed at securing the farthest end points of a corporate IT network, from focused malware attacks and other ransomware intrusions. Previously, there was a concept of “Patient Zero”, a considered acceptable risk. Since, the variety of the malwares was so few, it was considered alright, if few organizations were at risk due to a newly designed virus. The only way to prevent further attacks was to develop malware specific signatures. However, with the stretch of data landscape across seas and oceans, this signature based security system, has no relevance in today’s business scenario. With exponential increase in attacks, every end point in the network is a potential threat. Therefore, an advanced next generation, approach method is essential, which is detection based, rather signature based. One such trend is machine learning or known as local point analysis.
This is a multi method approach, which incorporates the best practices into one single application methodology. The threat matrix indicates primarily two attack vehicles, malware and exploits. Malwares are self executable program, which can be placed at different nodes of the network. Exploits are data files, which are aimed at the weakness of software programs, giving the attacker the leverage of remote operation. Therefore, prevention from these harmful threats needs a specialized multi-dimensional approach, which works in both online and offline mode. The method should be a preventive as well as a proactive one, with on-site and cloud security cover capabilities. Due to the poles apart nature of malwares and exploits, no single method can be of any help. The idea is to neutralize the threat, before it can affect the end point devices like the laptops, desktops, tablets, etc.
It is important for the security agent, to shrink the attack surface by providing maximum coverage to the possible malware infection at entry points. A centralized security solution, seems to be just not good enough to contain the latest malware threats, which has increased many folds, due to the organization policies like BYOD (Bring your own device) and work from home concepts. It becomes essential for the end point device to filter the threat, before the user connects to the centralized corporate system or network. Maximum security load should be on the end point device, so that the malicious attacks can’t get past the defenses of the main system. With end point approach, the threat does not escalate to the central level; any data loss can be quickly recovered from the main organizational server.
It is also imperative for the organizations, to have a close watch for the insider threat perception, which is made possible, with the security layer created at the nodal points. The end point devices can be programmed to have, user rights control, giving that extra bit of security to the core network. Since, application updates of the security software are received through the internet; it can be configured on each end point device, as per the requirement, based on the threat perception. However, even with end point security system, central administration’s role is ascertained strongly. Every log in from a remote device leaves a foot print in the form of a log or alert to the central server. This is governed by two most important traits of end point security, they are end point encryption and application control. Point encryption helps in the data security, in every folder, pen device, or USB devices connected to the end point device and application control prevents any authorized application to run, maintaining the integrity of security umbrella.
