Incident Response (IR) is the strategy used to handle security incidents to minimize harm to an organization and enhance the restoration of impacted services or operations. IR endeavors adhere to a plan, which serves as the directives outlining the response protocols and the responsibilities of various team members. IR has evolved into a requisite for organizations encountering escalating threat levels, and this chapter deliberates on its significance.

Focusing on the transformation and then the dilemmas of IR in this article, we will commence by examining how IR has progressed with threats and technological advancements. Subsequently, we will delve into the hurdles that IR teams confront currently, particularly concerning evaluating existing security levels in the organization, predicting and safeguarding systems from future threats, participating in legal processes linked to cyber-attacks, unifying the organization during crises, and integrating all security endeavors. The following principal topics will be discussed:

• The progression of incident response
• Hurdles confronted by incident response
• What is the necessity of incident response?

Commencing with an exploration of recent historical context to understand how IR has transformed over time.

The realm of cybersecurity threats

With the omnipresence of continuous connectivity and contemporary technological advancements, threats are swiftly evolving to exploit various facets of these technologies. Every device is susceptible to attacks, and with the Internet of Things (IoT), this has materialized. The IoT has witnessed increased utilization of digital communication and the heightened transmission of data through digital platforms augments the peril of data interception by malevolent entities. Widespread surveillance through digital devices is also a recent threat due to the heightened use of smartphones. Governments can now conduct digital surveillance on their populace under the guise of providing security against potential terrorist menaces. Malefactors can deploy similar tactics to the detriment of the targeted victims. In 2014, ESET, an internet security firm, reported 73,000 unsecured security cameras with default passwords.

Deciphering the attack terrain

In unequivocally simple terms, the attack surface embodies the totality of all conceivable vulnerabilities that, if exploited, can permit illicit access to the system, data, or network. These vulnerabilities are frequently also referred to as attack vectors, and they can range from software to hardware, to a network, and to users (the human aspect). The likelihood of being attacked or compromised is directly proportional to the magnitude of attack surface exposure. The higher the count of attack vectors, the broader the attack surface, and the greater the risk of compromise.

To illustrate the expanse of an attack surface and its exposure, let’s consider MITRE’s Common Vulnerabilities and Exposures (CVE) database, here: https://cve.mitre.org/cve/. The database furnishes a catalog of cybersecurity vulnerabilities that have been targeted in the past to alert organizations should they employ the same software or hardware systems. It encompasses 108,915 CVE entries at present, identified over the past few decades. Undoubtedly, many of these have been remedied, but some may still persist. This substantial figure accentuates the magnitude of the exposure risk.

Any software running on a system can potentially be exploited through software vulnerabilities, either remotely or locally. This particularly applies to software that is internet-accessible, as it is more exposed, and the attack surface is considerably larger. Frequently, these vulnerable applications and software can culminate in the compromise of the entire network, posing a threat to the data it houses. Moreover, there is an added risk that these applications or software are often susceptible to: insider threats, wherein any authenticated user can access unprotected data due to inadequately implemented access controls.

An attack surface may be susceptible to network assaults that can be classified as either passive or active, contingent on the nature of the attack. These assaults can compel network services to collapse, rendering services temporarily inaccessible, enabling unauthorized access to the data traversing the network, and causing other adverse business repercussions.

In an instance of a passive attack, the network might be surveilled by the adversary to seize passwords or acquire sensitive information. Throughout a passive attack, an attacker can leverage network traffic to intercept communications.Among fragile systems and pilfer data. This task can be carried out covertly, unbeknownst to the user. Conversely, in the event of an active assault, the opponent will endeavor to evade the security mechanisms by utilizing malware or alternative variations of network-related susceptibilities to infiltrate the network properties; active attacks may result in the revelation of information and critical documents. These assaults can also precipitate Denial-of-Service (DoS) assaults. Some common classes of intrusion vectors include:

• Schemes of social engineering
• Incidents of drive-by downloads
• Harmful URLs and scripts
• Browser-centered onslaughts
• Assaults on the distribution network (a pattern that is on the rise)
• Network-driven intrusion vectors

Verizon data breach report

To delve deeper into this subject, I would strongly recommend accessing and reviewing the Verizon data breach reports: https://enterprise.verizon.com/resources/reports/dbir/.

The Verizon breach report outlines that cyber attackers’ strategies and incentives have altered minimally over the past five years, with 63% of breaches mounted for financial purposes and 52% involving hacking. Ransomware invasions constitute nearly a quarter of malware-related attacks, and breaches often linger undiscovered for extensive durations, with 56% requiring several months or more to be apprehended. Typically, by the time a breach is unearthed, the destruction has already transpired.

The Verizon data breach report should seize your attention on three fronts. Awareness concerning these areas will aid in constructing a more robust IR blueprint, a subject that will be tackled in depth subsequently in this publication:

1. Misconfigurations emerge as the swiftest escalating threat demanding rectification
2. Vulnerabilities are frequently patched sluggishly, leading to breaches
3. Assaults targeting web applications have emerged as the most rapidly expanding category

To counter the myriad threats besieging an organization’s threat landscape, contemporary IT security defense necessitates a stratified system: a singular approach to security no longer suffices. In the occurrence of a network infringement, the afflicted individual or entity can endure significant repercussions, including financial ramifications, operational disruptions, and erosion of trust. The frequency of breaches has surged for assorted reasons in the recent past. The avenues of attack prompting these breaches may vary, encompassing viruses, Trojans, tailored malware for targeted incursions, zero-day attacks, or even internal hazards.

The network of interconnected devices is expanding with each passing day, escalating the potential exposure. This risk escalation is no longer contingent on the size of businesses. Within the modern cyber realm, it is challenging to ascertain the vulnerability of any network or application to attacks, underlining the paramountcy of cultivating a sustainable, reliable, and effective network infrastructure and applications. Adequately configured systems and applications will mitigate the likelihood of infiltration, even though eradicating the risk completely may remain unattainable. Nonetheless, this publication aims to provide insights into the realm of cybersecurity, underscore the threats digital networks and technologies pose to individuals and corporations, and furnish guidelines for fortifying preparedness against such menaces.

Now that we have delineated the cybersecurity backdrop and the significance of the threat landscape, let us pivot to a pivotal facet of this publication: what exactly constitutes incident response?

What ensues is a pertinent excerpt spotlighting the elements that mold an organization’s threat landscape:

The progression of incident response

The widely held belief concerning the genesis of hacking situates its origins in the 1960s, coinciding with the advent of modern computers and operating systems. To debunk this notion, the subsequent section briefly delves into the history of data breaches to delineate the context encompassing the contemporary attack milieu.
