IMPLEMENTING EASM IN YOUR ORGANIZATION Without an External Attack Surface Management or EASM program in place, there is a good chance that your external assets will become vulnerable at some point. This article will explain why this is the case and how we can defend against it.
AN EASM PROGRAM IS DIVIDED INTO FOUR STAGES: DISCOVERY This phase is concerned with mapping out all of your company's assets and determining your attack surface. This discovery phase for attack surface management solution, also known as reconnaissance or OSINT, frequently involves identifying DNS records, SSL certificates, cloud-based systems, applications, APIs, subdomains, and IP addresses, among other things.
ASSESSMENT It is critical to understand whether your externally facing assets by attack surface monitoring and endpoints can be exploited or are associated with a known risk. This stage can be difficult for a single security team to manage; this is where a dedicated group of ethical hackers can ensure continuous, full breadth and depth coverage, as well as a reduction in false positives and false negatives.
PRIORITIZATION Before you start fixing things, you should classify and categorise the risk associated with your exposed assets, because not everything will be a critical risk to your business. This phase assists you in determining where to direct your efforts and attention first, as well as the next best steps in addressing potential risks at all times.
REMEDIATION This is where you can take action and see measurable results, such as reducing the attack surface by removing unused assets from the internet or closing out a vulnerability . https://www.ctm360.com/external-attack-surface-management/
