How does phishing mail work and what impact does it have on businesses?
In the era of the technological boom, phishing scams are no longer badly formatted emails, but precisely targeted attacks (Spear Phishing) backed with the analysis of human behaviour in getting people to click. Fraudsters have taken cyberattacks to new levels of success, fooling even the savviest of employees. With the widespread phenomenon of automated click behaviour, it becomes hard for staff to police every email increasing the chances of a security breach. Employee errors are the #1 gateway to ransomware disasters, leading top tier businesses to adopt Endpoint Detection and Response to solidify their security posture.
“Phishing, the most common threat vector, is involved in 36% of data breaches.”
According to Verizon’s 2021 Data Breach Investigations report.
What is EDR and why is it the best?
EDR is an integrated solution that records real-time activities and events taking place on endpoints and all workloads with rule-based automated response and analysis capabilities. This provides the security teams with in-depth visibility they need to uncover incidents that may not otherwise been detected. An EDR solution provides continuous and comprehensive visibility into what is happening on endpoints in real time.
Modern EDR architecture tightly integrates with mail gateway solutions and firewall systems to detect, analyse, and block advanced threats before they reach employee inboxes. This in turn provides unified platform experience, including ransomware and other email viruses and URL’s. Organisations can detect malicious behaviour across all vectors and rapidly eliminate threats with autonomous response capabilities across enterprise attack surfaces.
The sophistication of modern malware is evolving at an increasing speed to which the traditional Antivirus (AV) signature-based detection is no longer effective. AV solution relies on the coded database of “bad” files to which they try match the recognised threat. However, due to the unique and everchanging malware infrastructure that is being pushed by scammers, these files can bypass antivirus undetectably. EDR on the other hand incorporates AV and other endpoint functionalities and can detect trends and other indicators of a successful incursion.
Companies have less than 30 minutes after employee error to prevent malicious ransomware moving laterally and infecting other devices. EDR has a quick response capability and can create an alert within a short time frame. For example, if an end user opens a spear phishing email and inputs their credentials to a seemingly legitimate website, the EDR solution will be able to monitor, alert the security team and prevent the attacker from logging into the endpoint- even under the guise of a legitimate sign in.
What should you look for in EDR solutions?
- Endpoint Visibility: Real-time visibility across all your endpoints allows you to view adversary activities, even as they attempt to breach your environment, and stop them immediately.
- Threat Database: Effective EDR requires massive amounts of telemetry collected from endpoints and enriched with context so it can be mined for signs of attack with a variety of analytic techniques.
- Behavioural Protection: Relying solely on signature-based methods or indicators of compromise (IOCs) lead to the “silent failure” that allows data breaches to occur. Effective endpoint detection and response requires behavioural approaches that search for indicators of attack (IOAs), so you are alerted of suspicious activities before a compromise can occur.
- Insight and Intelligence: An endpoint detection and response solution that integrates threat intelligence can provide context, including details on the attributed adversary that is attacking you or other information about the attack.
- Fast Response: EDR that enables a fast and accurate response to incidents can stop an attack before it becomes a breach and allow your organization to get back to business quickly.
- Cloud-based Solution: Having a cloud-based endpoint detection and response solution is the only way to ensure zero impact on endpoints, while making sure capabilities such as search, analysis and investigation can be done accurately and in real time.
To take your EDR a step further SentinelOne’s ActiveEDR provides analysts with real-time, actionable correlation and context and lets security analysts understand the full story of what happened in their environment. Storyline automatically links all related events and activities together an attack storyline with a unique identifier. This allows security teams to see the full context of what occurred within seconds rather than needing to spend hours, days, or weeks correlating logs and linking events manually. It is the most talked about solution in the cybersecurity world due to being the first EDR that is truly active.
ActiveEDR constantly draws stories of what is happening on the endpoint. Once it detects harm, it is capable of mitigating not only malicious files and operations but the entire ‘storyline’. ActiveEDR knows the full story, so it will mitigate this at run time, before encryption begins. It works by giving each of the elements in the story the same TrueContext ID. These stories are then sent to the management console, allowing visibility and easy threat hunting for security analysts and IT administrators.
