An organization&#8217;s or system&#8217;s entire vulnerable area is called its attack surface. It further consists of every point of entry that an unauthorized user could utilize to get inside the network. It can be difficult to learn how to conduct thorough external attack surface analysis and management on your own, particularly in large organizations with a variety of user permission levels.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-attack-surface\"><span id=\"attack-surface\">Attack Surface<\/span><\/h2>\n\n\n\n<p>The attack surface measures the total number of entry points (also called &#8220;attack vectors&#8221;) through which sensitive information can be stolen from a computer system. Protection is also simpler if there is less surface area to attack. Organizations need to keep an eye on their attack vectors to spot and stop threats as soon as they emerge. To further lessen the likelihood of a successful cyberattack, they should try to reduce the attack surface area. However, this becomes more challenging as they increase their online presence and adopt cutting-edge technologies.<\/p>\n\n\n\n<p>Both the digital and physical components make up the attack surface.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-1-digital-attack-surface\"><span id=\"1-digital-attack-surface\">#1. Digital Attack Surface<\/span><\/h3>\n\n\n\n<p>Every piece of hardware and piece of software that connects to a company&#8217;s network is part of the digital attack surface area. Websites, servers, code, apps, and shadow IT\u2014where users get around IT to use unapproved software or hardware\u2014are some examples of these.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-2-physical-attack-surface\"><span id=\"2-physical-attack-surface\">#2. Physical Attack Surface<\/span><\/h3>\n\n\n\n<p>Desktops, hard drives, laptops, mobile phones, and USB drives are all part of the physical attack surface. Therefore, there are many potential entry points for physical attackers, including lost or stolen hardware containing sensitive information, users jotting down passwords on paper, and actual break-ins.<\/p>\n\n\n\n<p>Through access control and surveillance, businesses can reduce their physical attack surface. Disaster recovery protocols and policies also need to be put into practice and tested.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-common-attack-surface-vulnerabilities\"><span id=\"common-attack-surface-vulnerabilities\">Common Attack Surface Vulnerabilities<\/span><\/h3>\n\n\n\n<p>Any area on a network where a data breach could occur is considered a common vulnerability. This covers both hardware\u2014such as computers, smartphones, and hard drives\u2014and human error\u2014where users reveal personal information to hackers.&nbsp;<\/p>\n\n\n\n<p>Weak <a href=\"https:\/\/businessyield.com\/tech\/apple\/mac\/how-to-find-saved-passwords-on-mac\/\" target=\"_blank\" rel=\"noreferrer noopener\">passwords<\/a>, insecure email, unprotected ports, and neglected software updates all leave users and businesses wide open to attack. Without proper web-based protocols, hackers can perform man-in-the-middle (MITM) attacks and steal sensitive information.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-to-define-your-attack-surface-area\"><span id=\"how-to-define-your-attack-surface-area\">How To Define Your Attack Surface Area<\/span><\/h2>\n\n\n\n<p>Define and map the attack surface before beginning any visualization. This means looking for possible weaknesses, evaluating vulnerabilities, and figuring out user roles and permission levels. Assessing a company&#8217;s exposure to risk begins with a thorough inventory of its attack surface, which can include such things as firewalls, switches, file servers, desktops, laptops, smartphones, and <a href=\"https:\/\/businessyield.com\/tech\/technology\/the-best-home-printers\/\" target=\"_blank\" rel=\"noreferrer noopener\">printers<\/a>.<\/p>\n\n\n\n<p>The next step is for them to classify all potential places for storing their company&#8217;s data and separate it into cloud, device, and on-premises systems. In this way, businesses can determine which employees have access to what information and resources, as well as the extent of those employees&#8217; <a href=\"https:\/\/businessyield.com\/tech\/cyber-security\/privileged-access-management\/\" target=\"_blank\" rel=\"noreferrer noopener\">privileges<\/a>. By doing so, they are better able to comprehend the nuances of user and departmental behavior and to organize potential points of attack according to factors like function and risk.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-attack-surface-management\"><span id=\"attack-surface-management\">Attack Surface Management<\/span><\/h2>\n\n\n\n<p>The term &#8220;attack surface management&#8221; describes the process of keeping an eye out for potential cyberattacks to prevent them in the future. It also maps the attack surface and reduces attack success with risk assessments, security controls, and security measures.<\/p>\n\n\n\n<p>In addition, it is critical to test for vulnerabilities and keep an eye on an attack surface&#8217;s performance after mapping it. Monitoring your online and offline resources for security flaws is also an integral part of attack surface management. The goal is to reduce the likelihood of an attack happening to you. Benefits of effective attack surface management include but are not limited to, the following:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Locate high-risk areas for vulnerability testing.<\/li>\n\n\n\n<li>Check for changes and new attack vectors.<\/li>\n\n\n\n<li>Determine who can access each system part.<\/li>\n\n\n\n<li>Counter-targeted cyberattacks<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-attack-surface-reduction-and-management-tools\"><span id=\"attack-surface-reduction-and-management-tools\">Attack Surface Reduction and Management Tools<\/span><\/h2>\n\n\n\n<p>Organizations can use a variety of tools to monitor their attack surface, identify current and future attack vectors, and take steps to eliminate or protect against them. These tools can help achieve this visibility:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-1-inventory-management\"><span id=\"1-inventory-management\">#1. Inventory Management<\/span><\/h3>\n\n\n\n<p>Organizations can store known systems with this tool. Usually, this process begins with &#8220;asset discovery,&#8221; or a systematic search for and inventory of all relevant IT resources.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-2-vulnerability-management\"><span id=\"2-vulnerability-management\">#2. Vulnerability Management<\/span><\/h3>\n\n\n\n<p>These programs probe the Internet and an organization&#8217;s networks for security flaws.

External Risk Ratings<\/span><\/h3>\n\n\n\n<p>Specifically, this means welcoming periodic audits of the company&#8217;s outward-facing security from independent third parties.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-4-red-teaming-and-penetration-testing\"><span id=\"4-red-teaming-and-penetration-testing\">#4. Red Teaming and Penetration Testing<\/span><\/h3>\n\n\n\n<p>Teams like these are invaluable to surface attackers because of the information they provide regarding attack vectors. These findings aid in determining which attack vectors are most pressing to address to lower the attack surface.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-attack-surface-analysis\"><span id=\"attack-surface-analysis\">Attack Surface Analysis<\/span><\/h2>\n\n\n\n<p>To improve your organization&#8217;s security, an attack surface analysis can give your team a glimpse into your IT setup from the eyes of a potential intruder. An attack surface analysis checklist can help you find security holes and catalog all the ways your business could be compromised. It entails keeping an eye on the vulnerable areas and securing them so that hackers and other malicious actors can not get in.<\/p>\n\n\n\n<p>The purpose of an attack surface analysis is to identify and catalog potential entry points into a system. It helps businesses locate potential weak points and open doors for attackers to exploit.<\/p>\n\n\n\n<p>With the aid of attack surface analysis, businesses can pinpoint vulnerable spots and high-risk areas where additional security testing is needed. This analysis can also be used to learn when upgrades to the infrastructure introduce new vulnerabilities. Attack surface analysis can be done manually with the aid of penetration testers and security architects or automatically using a variety of different tools.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-attack-surface-analysis-steps-nbsp\"><span id=\"attack-surface-analysis-steps\">Attack Surface Analysis Steps&nbsp;<\/span><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Locate any possible points of entry and weak points in the infrastructure of the company.&nbsp;<\/li>\n\n\n\n<li>Assess the possible consequences of the found vulnerabilities, giving high-risk entry points that need quick attention priority.<\/li>\n\n\n\n<li>Figure out what an attacker could do to exploit the holes you found.<\/li>\n\n\n\n<li>Create a plan to address the identified risks.&nbsp;<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-reducing-attack-surface\"><span id=\"reducing-attack-surface\">Reducing Attack Surface<\/span><\/h2>\n\n\n\n<p>Reducing an organization&#8217;s attack surface involves finding and fixing all the places where hackers could gain access to its computer systems and networks. This can involve limiting the possible openings for exploits and vulnerabilities by putting in place security measures like firewalls, intrusion detection and prevention systems, and access controls. Additionally, it can involve conducting routine security audits to find and fix any newly discovered vulnerabilities, as well as offering staff education and awareness campaigns to inform them of cybersecurity best practices.<\/p>\n\n\n\n<p>These five steps will help organizations reduce their attack surface.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-1-implement-zero-trust-policies\"><span id=\"1-implement-zero-trust-policies\">#1. Implement Zero-trust Policies<\/span><\/h3>\n\n\n\n<p>The zero-trust security model guarantees that only authorized users have access to sensitive data when needed. As a result, organizations can rest assured that only authorized users are gaining access to their networks, which strengthens the entire infrastructure and reduces the number of entry points.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-2-eliminate-complexity\"><span id=\"2-eliminate-complexity\">#2. Eliminate Complexity<\/span><\/h3>\n\n\n\n<p>Complexity that is not needed can lead to missteps in management and policy that give hackers access to private company information. To streamline their network, businesses should remove unused applications and hardware.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-3-scan-for-vulnerabilities\"><span id=\"3-scan-for-vulnerabilities\">#3. Scan for Vulnerabilities<\/span><\/h3>\n\n\n\n<p>Scanning and analyzing networks regularly helps businesses find problems quickly. It is critical to have complete attack surface visibility to prevent issues with cloud and on-premises networks and to ensure that only authorized devices can access them. In addition to finding exploitable holes, a thorough scan should demonstrate how those holes can be used to compromise endpoints.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-4-segment-network\"><span id=\"4-segment-network\">#4. Segment Network<\/span><\/h3>\n\n\n\n<p>By dividing their networks into smaller, more manageable pieces, businesses can in reducing the attack surface area. These consist of devices such as firewalls and tactics like micro-segmentation, which partitions the network into smaller sections.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-5-train-employees\"><span id=\"5-train-employees\">#5. Train Employees<\/span><\/h3>\n\n\n\n<p>Defending against cyberattacks starts with employees. They will be better prepared to recognize the warning signs of a phishing email or social engineering attack if they receive regular cybersecurity awareness training.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-external-attack-surface-management-nbsp\"><span id=\"external-attack-surface-management\">External Attack Surface Management&nbsp;<\/span><\/h2>\n\n\n\n<p>A company&#8217;s &#8220;external attack surface management&#8221; (EASM) is its process of identifying, assessing, and resolving vulnerabilities and threats to its externally accessible digital assets. EASM includes a range of tasks, including asset identification, vulnerability assessment, threat intelligence tracking, deployment of security controls, and ongoing monitoring to maintain a strong security posture and quickly address new threats.<\/p>\n\n\n\n<p>The objective of EASM is to decrease the number of weak points and potential entry points that hostile actors could use to gain unauthorized access, contaminate data, or interfere with services. An organization&#8217;s vulnerability to cyber attacks, data breaches, and reputational harm can be mitigated by taking measures to control the external attack surface.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-does-external-attack-surface-management-work\"><span id=\"how-does-external-attack-surface-management-work\">How does External Attack Surface Management Work?<\/span><\/h2>\n\n\n\n<p>Common practices for an external attack surface management (EASM) platform include the use of both automated tools and human analysis. Automated tools investigate the company&#8217;s online presence from the outside, looking for weak spots and entry points to the network. These instruments may use a variety of techniques, including port scanning, vulnerability analysis, web application testing, and OSINT (open-source intelligence) analysis.<\/p>\n\n\n\n<p>Manual analysis can validate and interpret scan results to supplement automated tools. Experts in the field of security investigate the data, examine the surrounding circumstances, and weigh the risks that come with the vulnerabilities that have been uncovered.<\/p>\n\n\n\n<p>After discovering a security hole, businesses can take steps to fix it by installing patches, adjusting settings on security tools, increasing the security of access points, and so on. The best way to stay ahead of developing threats and maintain continuous protection is to conduct regular scans and monitoring of the external attack surface.<\/p>\n\n\n\n<p>Gathering and analyzing threat intelligence is an example of a preventative step that may be the best way for businesses to stay abreast of the latest attack methods, vulnerabilities, and threat actors. In addition, you subscribe to threat feeds and read security blogs.\u00a0<\/p>\n\n\n\n<p>As a whole, EASM is a methodical strategy for protecting an organization&#8217;s external attack surface by systematically discovering, analyzing, and fixing security flaws and threats to lessen the likelihood of successful cyber attacks.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-why-is-external-attack-surface-management-important\"><span id=\"why-is-external-attack-surface-management-important\">Why is External Attack Surface Management Important?<\/span><\/h2>\n\n\n\n<p>Effective cybersecurity requires constant attention to the management of the external attack surface.
