The threat landscape is increasingly becoming more dangerous. According to 2021 Mid-Year Cyber Threat Landscape report, ransomware attacks increased by 800% between 2019 and 2020, and Ponemon’s 2020 State of Endpoint Security Risk report stated that 80% of successful breaches are caused by previously unknown malware and zero-day attacks. The tools used by many businesses aren’t up to the task of defending against more complex threats.
Endpoint Detection and Response (EDR) seems to be one of the most important aspects of any cybersecurity plan, on the surface. Increasing security at entry points to systems and networks should help a company reduce risk. Malware and ransomware attacks, however, continue to have a significant impact on supply chains, critical services, and the economy as a whole. It’s past time to take a closer look at how businesses can protect themselves from cyber-threats.
A reactive approach is not enough
The most significant disadvantage of EDR is that it is a reactive approach. Traditional EDR depends on behavioral analysis, which means the threat has already been executed on the endpoint, and it’s a race to stop it before it causes any damage.
SOC productivity is critical to defending the company at a time when there is a shortage of skilled resources. A typical EDR generates a large number of alerts and false positives, limiting the ability of the SOC team to do preventative actions such as patching and hardening systems.
Serious threats can easily get lost, making it more likely that threat actors will remain undetected for longer periods of time.
As a result, visibility across all endpoints is vital to an organization’s security. However, businesses may not know if all of their endpoints are instrumented, resulting in gaps. Trends like remote working have made it more difficult to ensure that every device is covered.
Organizations must have complete visibility across all endpoints connected to the network, in order to be truly effective.
To prevent more attacks from being carried out, a prevention-first approach is required. Every security-minded organization should strive for prevention. To get there, they will need to take steps that will allow them to build on the tools they already have. Human factors, such as training, must be considered. In most circumstances, a once-a-year presentation is all that many organizations provide in terms of security awareness training. Best practises must also be reinforced on a regular basis, and security standards must be enforced. Also, it is important to keep an eye out for signs of insider threats, both accidental and intentional; Research studies consistently ranks this risk towards the top of the list of security dangers that businesses face on a daily basis.
In terms of technology, security teams must examine who has access to each system and ensure that users are who they claim to be by enabling and mandating two-factor or Multi-Factor Authentication (MFA). They need to use EDR tools and other security solutions for visibility into flaws throughout the environment, whether it’s vulnerability exploiting, malware attacks, or “Living off the Land” threats that may already be in systems hiding in legitimate processes.
