External attack surface management
Our attack surface management tool uncover your known and unknown digital assets like a hacker would and reduce application risks with quantified attack surface exposure
Mapping your web application attack surface
External facing applications provide crucial revenue streams and are the main source for connecting you with your customer base. However, they can become a source of exploitation for hackers if they contain vulnerabilities. With application development evolving at high speed, security leaders must understand the attack vectors and unknown assets that hackers could use to enter the system.
Our external attack surface management tool is the only solution to provide real time visibility of your application attack surface whilst pinpointing potential cyber risks in your digital ecosystem. The tool enables organizations to visualize their security exposure against the most common entry points for application attacks and highlight areas that require immediate attention for risk management.
Common attack vectors and security exposure
Using HTTP websites without encryption and unsecured redirects can expose your sensitive data to hackers and lead to credential stuffing. Identify if correct authentication exists and apply restriction controls to prevent unauthorized access
Page creation method
Developing a website with insecure code means there are more potential vulnerabilities to exploit. Scout detects out of date code language and vulnerable components in your application helping you ensure a secure release and reduce cyber risks
Degree of distribution
The sheer number of application pages and unknown assets is a breeding ground for exploitable vulnerabilities and a challenge for risk management. Easily identify every page interlinking every domain to uncover potential entry points for hacker exploits
Authentication is the process of verifying the identity of a user accessing your application in real time. Restricting access to sensitive data is critical to keeping the bad guys out and reducing your application risk
The attack surface increases with the number of different input fields you have on a web application and can lead to a range of Cross-Site Scripting attacks if these are left unaddressed before production
Active content technologies
When an application runs scripts the content becomes active. You need to know if your web app has been developed using vulnerable and outdated active content technologies to reduce security exposure
Cookies are an essential security control for website security by monitoring session activity in real time and ensuring anyone who sends requests to your website are authorized and keeps hackers away
Usage of HTTP port 80 rather than the more secure HTTPS port 443 makes your application susceptible to unauthorized access. It’s important for security teams to identify open ports and close down those not in use
How we assess your application attack surface
Your guide to attack surface management
An attack surface is all the software, cloud and application assets (known or unknown) that process or store data that are accessible on the internet. It’s the sum of attack vectors that attackers could use to penetrate and manipulate a system to extract data. These assets are internet exposed and outside the scope of firewall and endpoint protection. It is critical for organizations to understand and proactively reduce the attack surface to prevent cyber security risks stemming from shadow IT and application vulnerabilities
An attack surface is the total sum of vulnerabilities or security exposure that can be exploited to carry out potential cyber attacks, which is growing in size with digital transformation. Whereas attack vector is the means that is used by attackers to access or infiltrate the target system. Application attack vectors can take many different forms from misconfigurations, cross site scripting, SQL injection to broken authentication. Organizations should have a continuous process to identify these potential attack vectors and implement appropriate security controls to prevent them from being exploited.
Common application attack vectors include injection, broken authentication and sensitive data exposure as highlighted by OWASP Top 10 2017, other attack vectors range from buffer overflow and cross site request forgery (CSRF) to local file inclusion. Also pay attention to old and new CWE vulnerabilities in your environment to keep your applications as secure as their speed of development
Modern applications are complex and hard to secure - with every line of code, software component and API being a potential attack vector. To reduce the attack surface, start with visibility - identify what you own and where they are exposed; assess your applications against common attack vectors to locate open pathways and security weaknesses that could give hacker a foothold; finally use risk-based insight to prioritize software vulnerability remediation and protect your data. In the age of DevOps, this process should be done continuously through automation to ensure speedy releases
External attack surface management (ESAM) tools are essential to automate the discovery of vulnerable applications that poses critical risk for your organization. The main components of an EASM tool include:
Application discovery - map the entire inventory of web services in your organization’s digital footprint and classify them by type, platform and business criticality
Vulnerability analysis - assess every application you own with a blackbox approach to visual weak spots that requires attention
Actionable risk scoring - Understand your security exposure from a hacker’s view with quantifiable risk ratings to prioritize fixes
Continuous monitoring for known vulnerabilities and misconfigurations to keep them secure as changes are made
Utilizing an external attack surface management tool like Scout can help cut down the time taken to discover the complete chain of applications that you are connected to and pinpoint potential security issues from the ‘outside in’ (including those you didn’t know existed) to help security teams build a clear plan for early mitigation for vulnerabilities at risk.
Application discovery and inventory - gather and uncover known and unknown assets and domains that you may have missed; attack vector analysis - assess your application against the common vectors to locate open pathways; Actionable risk scoring - visualize your security exposure to pinpoint most critical the biggest cyber risks; Continuous monitoring - continuously monitor the attack surface to improve long-term risk management
