Key Components of an Incident Response Plan

Incident Response Evolution and Current Challenges Part 1

security analysts product security manager specialist manager security specialist product specialist product security manager security specialist product manager What does a security specialist do? What is the role of a security professional?

Incident Response (IR) is the approach used to manage security incidents in order to reduce the damage to an organization and improve the recovery of affected services or functionalities. IR activities follow a plan, which is the set of directions that outline the response procedures and the roles of different team members. IR has become a necessity for organizations facing rising threat levels, and this chapter discusses its importance.

With the focus of this article being the evolution and then the challenges of IR, we’ll begin by looking at how IR has evolved with threats and advancements in technology. We’ll then look at the challenges that IR teams face today, especially with the tasks of assessing current levels of security in the organization, anticipating and protecting systems from future threats, being involved in legal processes relating to cyber-attacks, uniting the organization during crises, and integrating all security initiatives. We’ll cover the following main topics:

• The evolution of incident response
• Challenges facing incident response
• Why do we need incident response?

We’ll begin by exploring some recent history, and how IR has evolved over time.

The cybersecurity threat landscape

With the prevalence of 24-hour connectivity and modern advancements in technology, threats are evolving rapidly to exploit different aspects of these technologies. Any device is vulnerable to attack, and with the Internet of Things (IoT) this became a reality. The IoT has seen increased usage of digital communication and the increased transfer of data via digital platforms increases the risk of data interception by malicious individuals. Pervasive surveillance through digital devices is also a recent threat with the increased use of smartphones. Governments can now engage in digital surveillance of their citizenry with the excuse of providing security against potential terrorist threats. Criminals can also do similar tasks to the detriment of the targeted victims. In 2014, ESET, an internet security company, reported 73,000 unprotected security cameras with default passwords.

Understanding the attack surface

In very simple terms, the attack surface is the collection of all potential vulnerabilities that, if exploited, can allow unauthorized access to the system, data, or network. These vulnerabilities are often also called attack vectors, and they can span from software to hardware, to a network, and to users (which is the human factor). The risk of being attacked or compromised is directly proportional to the extent of attack surface exposure. The higher the number of attack vectors, the larger the attack surface, and the higher the risk of compromise.

Just to give you the extent of an attack surface and its exposure, let’s look into MITRE’s Common Vulnerabilities and Exposures (CVE) database, here: https://cve.mitre.org/cve/. The database provides a list of cybersecurity vulnerabilities that have been targeted in the past, to make organizations aware of them should they use the same software or hardware systems. It has 108,915 CVE entries at the time of writing, which have been identified over the past few decades. Certainly, many of these have been fixed, but some may still exist. This huge number indicates how big the risk of exposure is.

Any software that is running on a system can potentially be exploited using vulnerabilities in the software, either remotely or locally. This applies particularly to software that is web-facing, as it is more exposed, and the attack surface is much larger. Often, these vulnerable applications and software can lead to the compromise of the entire network, posing a risk to the data it is managing. Furthermore, there is another risk that these applications or software are often exposed to: insider threat, where any authenticated user can gain access to data that is unprotected due to badly implemented access controls.

An attack surface may be exposed to network attacks that can be categorized as either passive or active, depending on the nature of the attack. These can force network services to collapse, making services temporarily unavailable, allow unauthorized access to the data flowing through the network, and other negative business impacts.

In the event of a passive attack, the network might be monitored by the adversary to capture passwords, or to capture sensitive information. During a passive attack, an attacker can leverage the network traffic to intercept communications between sensitive systems and steal information. This can be done without the user even knowing about it. Alternatively, during an active attack, the adversary will try to bypass the protection systems using malware or other forms of network-based vulnerabilities to break into the network assets; active attacks can lead to the exposure of data and sensitive files. Active attacks can also lead to Denial-of-Service (DoS) type attacks. Some common types of attack vectors are:

• Social engineering scams
• Drive-by downloads
• Malicious URLs and scripts
• Browser-based attacks
• Attacks on the supply chain (which are becoming increasingly common)
• Network-based attack vectors

Verizon data breach report

To find out more about this topic, I would highly recommend that you download and read Verizon data breach reports: https://enterprise.verizon.com/resources/reports/dbir/.

According to the Verizon breach report, hackers’ tactics and motives have not changed much over the last 5 years, with 63% of breaches launched for financial gain, and 52% of breaches featuring hacking. Ransomware attacks account for nearly 24% of attacks involving malware, and breaches continue to take a long time to be detected, with 56% taking several months or longer to be discovered. And typically, by the time the breach has been discovered, the damage has already been done.

The Verizon data breach report should catch your attention in three areas. Knowledge of these areas will help you to build a better IR plan, which we will cover later in this book:

1, Misconfigurations are the fastest-growing risk that you need to address
2. Vulnerabilities are more often than not patched too slowly, leading to breaches
3. Attacks against web applications are now the fastest-growing category

To combat the many threats facing an organization’s attack surface, modern IT security defense should be a layered system: a single-layer approach to security is simply not enough anymore. In the event of a network breach, the victim individual or organization can sustain huge damage, including financial and operational implications, and loss of trust. In the recent past, the number of breaches has increased for various reasons. The attack vectors for these breaches could be many, such as viruses, Trojans, custom malware for targeted attacks, zero-day-based attacks, or even insider threats.

With every passing day, the network of connected devices is increasing, and, while this growth of connectivity continues to grow bigger, the risk of exposure is also increasing. Furthermore, it is no longer dependent on how big or small businesses are. In today’s cyberspace, it is hard to establish whether any network or application is prone to attacks, but it has become extremely important to have a sustainable, dependable, and efficient network system, as well as applications. Properly configured systems and applications will help reduce the risk of attack, but we might not ever be able to eliminate the risk of attack completely. However, this book will attempt to relay insight into the world of cybersecurity, highlight the dangers that digital networks and technology pose to individuals and companies, and provide guidelines on how to better prepare for such threats.

Now, having established the cybersecurity landscape and the relevance of the attack surface, let’s move on to a key element of this book: what is incident response?

What follows is a relevant excerpt, which indicates the various factors that shape an organization’s attack surface:

The evolution of incident response

The general notion regarding the origin of hacking is that it started in the 1960s, around the time of the invention of modern computers and operating systems. To disprove this notion, let’s next briefly explore the history of data breaches, to develop an idea of the context behind the modern attack environment.
