Or, in other words, it is the most <strong>vulnerable</strong> area of the system. This reveals the amount of security in the environment. If the attack surface is larger, the environment can be breached more easily. In that regard, it must be considered to keep the attack surface a small area. The concept is very important for software protection.</p>\n<p>So, in order to create systems that are secure, the attack surface should be as small as possible. There are a few ways to do this:</p>\n<ul>\n<li>The services that are employed by only a small group of individuals should be taken out. Meaning that there will be fewer attack vectors if there are fewer <strong>unnecessary features</strong>.</li>\n<li>There is <strong>code</strong> that is always operating within the system. By reducing the amount of it, there will be fewer attack vectors as well.</li>\n<li>Making fewer <strong>access points</strong> in the system will also result in fewer attack vectors.</li>\n</ul>\n<p>Attack vectors are network protocol flaws, or buffer overflows. They could also be <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-trojan/">trojans, <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-malware/">malware, adware, and other software that are based on the web. These attack vectors are within the attack surface.</p>\n<p>If a malicious actor would attack, he could manipulate or take the data out of the system and cause damage. Usually, attackers know where are all the devices in the system as well as how they operate. This way, the weakest points can be detected and imposed upon.</p>\n<p>However, even if you manage to reduce the attack surface, if the malicious actor did already get into the system - there is nothing you can do to prevent the incoming or already done <strong>damage</strong>. Besides, it&rsquo;s enough for the attacker to discover <strong>one</strong> weak point of the system to breach in.</p>","level":"medium","meta_title":"What is Attack Surface?
