What is Endpoint Security? Its Importance & How It Work


Endpoint Security

What is Endpoint Security?

Commonly referred to as endpoint protection, this is a type of approach specifically directed towards cyber security to define endpoints. Endpoints can be devices like laptops, mobiles, desktops, and even IOT devices (basically any computational devices that enable anyone to access any kind of corporate network from outside its firewall).

Gartner said, “Endpoint Protection Platform (EPP) is the key to achieve protection from any type of file-based malware attack, detect any suspicious activity and even provide investigation needed after any sort of security breach or alert”.

Importance of Endpoint Security

It becomes very crucial for corporate giants to focus on the security of the devices that the company uses as data security is one of the major focus points for any big firm. Another reason (not only from a corporate perspective) for which this becomes very essential is that any endpoint for any of internet user is directly or indirectly an entry point for an attacker with malicious intent. Keeping this fact aside, one should also note that endpoints will only increase in numbers. After the pandemic, the world is witnessing a huge shift towards the online mode of work culture, and in these times it becomes very prominent to keep the devices secure.

What is an EPP?

An EPP is one of the most efficient and effective ways to check various kinds of suspicious activities. These platforms are used by corporate giants to put leverage against the protection of servers, and IoT/ mobile devices and even do the same with the workstations/ work-floors. These complex platforms monitor almost everything (ranging from files to processes) including system activities even in non-working hours of the day. By providing the centralized type of management, a console is present for the server admins to monitor every aspect of the network and data flow.

Classifying the platform, furthermore, we can segregate it into three major types. They are mentioned as follows-

  • Traditional/ legacy approach

This type can be used to describe the offline and on-premise security structure of the company which is the backbone of all the cyber-data hosted locally on the local servers and storage.

  • Hybrid approach

With the current shift towards the framework where employees have to attend office from home, the traditional approach of service can’t provide the best protection to each and every device that employees work on, thus there is a recent shift in hybrid mode. This mode takes properties of both traditional as well as cloud-native solutions to provide the better of the two worlds.

  • Cloud-native approach

As the name suggests, this approach strictly falls under an off-premises security structure. Any server admin can remotely monitor all kinds of activities and sharing that happens between the employees as well.

How is it different from Antivirus Software?

Antivirus software is majorly a part of the whole endpoint security idea and is often termed as the most basic and low-level form of endpoint protection for any device. So when someone talks about the same, it is generally presumed that one must already have stable access to well-structured antivirus software. Antivirus anyways instead of using smart techniques like EDR (endpoint detection and response), only tells you about known malware, viruses, and general layman level of threats.

Functionality and Steps of the Cycle

There are multiple EP security tools available from various developers specifically designed for specific goals that one firm decides to achieve. In general, all the tools have the following chain of order to follow. Some of the major and common steps are as follows-

  • Prevention

Next-generation antivirus (NGAV), can be termed as a big brother of anti-viruses as antivirus software will limit itself to only checking similar bits of codes(malware) that are already known to the majority. Meanwhile, NGAV takes it one level above by using most

Efficient and advanced practices of the industry to identify the latest forms of malware. It basically reads all the data minutely like hashes and even URLs.

  • Detection

Prevention can only help the admin to stay vigilant but as we all know, no kind of defense is always perfect and thus detection stage comes into the picture. EDR programs and the platform provide continuous and vigorous surveillance of each update of the devices in real-time (as it is happening). It handles multiple types of fields like activity validation, alert notifications, suspicious activity monitoring and even investigation of the already happened security breach/ incident.

  • Threat eradication and threat AI

Despite the best-in-class automation that this app uses, attackers of the modern age still manage to breach the platforms sometime with the help of delicately crafted attacks. So, in that situation a team of experts generally takes control. The platform then acts as an assistant to the actual experts and it guides them through the whole process of the attack in order to back-trace the left out entry point and secure the same.

As a countermeasure to staying ahead of the attackers, well-crafted AIs are also entering the market in order to predict the type of attacks that are possible on a given specific type of company structure and even the structure and nature of their existing security arrangements.

Conclusion

To conclude, it is very important to understand the importance of data and the depth of security that comes with owning any kind of personal or professional data. Since everything is turning to “online mode”, it becomes very essential for a common man to keep his data (example- CVV number) safe. in the same manner, the corporate also needs to protect their’s as well as their client’s data safe in order to not face any kinds of loss in monitory terms and in terms of goodwill as well. Endpoint protection must be taken seriously by everyone to achieve complete cyber security at any given level of confidentiality.
