Almost no single day goes without hearing or reading a piece of news about cyberattacks. Still, the ubiquity of attacks and the ability of hackers to pull it off so effortlessly (at least that’s how it looks because of the frequency) leads back to the question – what are we doing wrong?

Many things such as lower than optimal budgets, lack of awareness among employees about possible cybersecurity threats, limited measures in place to tackle attacks, lack of proactive monitoring, and more. 

In this article, we will focus on the ways and means by which hackers can attack an organization and what you can do to bring down the different entry points in your network for hackers to enter and attack. Let’s start with an understanding of what an attack surface is and its importance, and then, move on to how you can bring it down. 

What is an Attack Surface?

Attack surface is the combination of different entry points that hackers can potentially use to attack your organization’s network. It includes all the vulnerabilities and the devices or endpoints that can potentially provide an entry point for hackers. 

Needless to say, the smaller the attack surface is, the lesser your chance to get attacked. This is why organizations strive to lower the area of their attack surface.

Now, on a practical note, attack surfaces are complex and widespread. In today’s world where work-from-home culture is highly prevalent, every device that connects to the organization’s network is a potential vulnerability. In this sense, the entire world is an attack surface for remote-model organizations.

Types of Attack Surfaces

Broadly speaking, an attack surface is categorized into physical and digital surfaces. 

• Physical Attack Surfaces Physical attack surfaces encompass the physical space of an organization and include all the servers, data centers, devices, sensors, and other endpoints. It also includes security door access, paper documents containing sensitive information, physical devices, and basically, anything that a hacker can physically come and steal.
• Digital Attack Surfaces Digital attack surfaces are your applications, ports, remote devices, and other endpoints that can be virtually used by a hacker to enter your organization’s network. Often, the digital attack surfaces include vulnerabilities such as poor password practices, lack of employee training on best security practices, unpatched software, lack of role-based access to sensitive information, liberal configuration settings, and more. 

Both the physical and digital attack surfaces must be kept to a minimum to stave off attacks.

How to Identify the Attack Surface Area?

The first step towards mitigating the possibility of an attack is to determine the size of your attack surface, so you know what measures should be put in place. This process of determining the size of your attack surface and all that it encompasses is called the attack surface analysis.

There are three broad steps for understanding your attack surface and they are:

• Visualization The first step is to create a map of all your devices, endpoints, physical spaces, and everything else that is a part of your organization’s network. This must include both digital and physical attack surfaces.  You can imagine this step to be more of an inventory collection or gathering exercise. 
• Looking out for Indicators The second step is to understand the possible indicators or vulnerabilities in the map that you visualized earlier. In this step, it’s a good idea to not just list down the different possible points of attack, but also jot down the strategies that could be used by hackers to enter the network through a particular endpoint. In this step, you can also include the necessary controls that are currently missing.
• As you can see, this step involves a detailed analysis of the strengths and weaknesses of your security system and the endpoints.
• Identifying Attacks This step is more of a retrospective analysis where you make a list of all the possible attacks that have happened and the strategy that hackers used each time to enter your network.

Armed with all this information, you are now set for a detailed attack surface analysis of what you should do and the strategies that you can leverage. 

Attack Surface Analysis

Attack surface analysis is the process of identifying the endpoints that can allow a possible attack. It is a detailed analysis of the above-mentioned steps, so you know the number of exploitable vulnerabilities within your organization and what you can do to mitigate them. At the end of this analysis, you must be able to identify the areas that must be tested or reviewed for security vulnerabilities. 

An attack surface analysis entails the following broad measures.

• Understand the vulnerabilities
• Inform the leadership/management about these vulnerabilities and their impact on the organization as a whole
• Find ways and means to mitigate the identified vulnerabilities
• Staying on top of how and when the attack surface area changes

Now that you have an idea of what an attack surface analysis is, let’s talk about the different strategies that you can use to achieve the above-mentioned aspects.

Attack Surface Analysis Strategies

Here’s a look at some strategies that can come in handy for your attack surface analysis.

Vulnerability Assessment

As the name suggests, this strategy is all about identifying and defining what a vulnerability is, identifying it, assessing the vulnerability for its impact, classifying the impact, and prioritizing them to beef up your network’s security. Many times, it can also include appropriate remediation recommendations to eliminate these vulnerabilities. 

Some threats that can be prevented with vulnerability assessments include SQL injection, poor authentication mechanisms, faulty password policies that lead to the creation of simple and easily guessable passwords, and more.

Vulnerability assessments can be classified into many types, with the prominent ones  being,

• Vulnerable Host Assessment This assessment includes identifying vulnerable devices and servers and includes patch management, outdated software, open ports, and more.
• Wireless and Network Assessment In this assessment, you look into the wireless connections and network vulnerabilities, especially the endpoints through which they can be accessed.
• Database Assessment This assessment includes assessing the security and authorization practices of databases, test and development environments, and more.
• Application Assessments In this assessment, you look into the codebase of applications and the possibility of security vulnerabilities. 

In all, vulnerability assessments can help you identify threats and vulnerabilities. 

Penetration Testing

Penetration testing or pen testing is the process of hiring ethical hackers to simulate an attack against your devices and network. The idea here is to get into the minds of hackers to understand how they are likely to attack your system. Accordingly, you can put the required security measures to prevent such attacks.

This proactive testing approach can also bring up the vulnerable practices and points from a security perspective, so they can be remediated at the earliest. 

Red Team and Blue Team

Another popular strategy is to use two teams called the Red Team and the Blue Team. Typically, the Red team includes ethical hackers who try to hack into your system while the Blue team is your security personnel who try to prevent the attack and mitigate its impact.

The idea here is to prepare your security team to quickly prevent and handle any cyberattacks that can come up.

Thus, these are some examples of attack surface analysis that you can undertake for your organization. 

At the outset, all of these analyses and practices can sound overwhelming. The good news is many attack surface analysis tools can ease this process for you.
