Incident Response Planning: A Critical Shield in Modern Cybersecurity

7/7/2024

One axiom remains constant in the ever-evolving cybersecurity landscape: "Prior planning prevents poor performance." This principle, sometimes colorfully expressed as "Proper preparation prevents piss-poor performance," encapsulates the essence of incident response (IR) planning. As cyber threats continue to escalate, the question isn't if an incident will occur but when. Let's delve into why IR planning is crucial and how it's shaping the future of digital security.

The Cybersecurity Landscape: Then and Now: Reflecting on the past decade, I see   the cybersecurity terrain has experienced a significant transformation. A decade ago, the outlook was dire: 85% of businesses hit by a security incident closed within a year, often within six months. Today, the situation is markedly different, and we must understand this evolution.

Critical Changes in Cybersecurity:
  1. Increased awareness and preparedness
  2. Reduced stigma around cyber attacks
  3. Improved recovery possibilities
  4. Enhanced trust retention post-incident (depending on compliance and breach specifics)

The Power of Proactive Preparation
An effective IR plan transcends merely investing in security measures. It's about strategic foresight and readiness. As cybersecurity professionals, our mission is to:
  • Help businesses identify potential threats
  • Develop comprehensive response strategies
  • Equip decision-makers with crucial data and insights
This proactive approach ensures that organizations are primed to respond swiftly and effectively when (not if) an incident occurs.

Real-World IR Plan Successes

Case Study 1: The Exchange Hack Incident
Scenario: A client was on the brink of launching a new system when their Exchange server fell victim to a widely-known hack, resulting in site encryption.
IR Plan in Action:
  • Rapid issue identification
  • Immediate halt to further changes
  • Structured approach following IR plan steps
  • Timely engagement with insurance and forensic experts
Outcome: Full recovery within one week, minimizing downtime and potential losses.

Case Study 2: Anomalous Behavior Detection with SOC
Scenario: A mid-sized healthcare client faced a potential security threat when a physician used a rarely-accessed VPN client.
IR Plan in Action:
  • Automatic access suspension triggered by SOC
  • IR manager followed protocol, contacting client leadership and the forensic team
  • A thorough verification process with the physician
Outcome: The incident was downgraded from a potential threat to benign activity, demonstrating the effectiveness of the IR system.

Integrating IR Plans into Organizational DNA
An IR plan isn't just a safeguard against significant breaches or ransomware attacks. It's a fundamental component of a company's operational framework, guiding responses to incidents of all scales. From business email compromises to minor anomalies, a well-structured IR plan ensures:
  1. Consistent response protocols
  2. Efficient resource allocation
  3. Minimized downtime and financial impact
  4. Enhanced stakeholder confidence
Preparedness is Power
The adage "failing to plan is planning to fail" couldn't be more apt in cybersecurity. A robust IR plan can mean the difference between an organization weathering a cyberstorm or succumbing to its aftermath. By weaving IR planning into the fabric of corporate culture, businesses can fortify their defenses against the inevitable challenges of our digital age.
Remember, knowledge isn't just power in cybersecurity—it's survival.

Why is an IR plan important?
An IR plan is crucial because it prepares an organization to handle cyber threats swiftly and efficiently, minimizing damage and downtime.
How often should an IR plan be updated?
It's recommended to review and update an IR plan annually or whenever there are significant changes in the organization's infrastructure or threat landscape.
What are the key components of an IR plan?
Key components include incident detection, containment strategies, eradication steps, recovery procedures, and post-incident analysis.
Can small businesses benefit from an IR plan?
Yes, small businesses are often targets of cyber attacks due to perceived vulnerabilities. An IR plan helps them respond to incidents effectively, protecting their operations and reputation.
How can an organization test its IR plan?
Organizations can conduct regular tabletop exercises, simulations, and live drills to test their IR plans and ensure all team members are prepared for actual incidents.

Security Operation Center (SOC) Overview

6/18/2020

I have to build many SOC teams in my professional career. In this post, I’d like to declutter some of the myths about SOC. Let’s start with the basics.

One of the most important questions is why your organization needs a SOC?

Enterprise often collects a large amount of data in the form of logs. Simply storing the data is not valuable. The humongous amount of information needs to be searched for malicious activities. If there is malicious activity, you need a human to respond to it intelligently. SOC team members will do the Detection, Investigation, and Response to the incident. Another critical aspect of the SOC team (often overlooked) is the post-incident reviews. 

What are the sub-team/sub-group in a SOC?

Key Roles in a SOC Team?
  • SOC Manager
  • Cyber Security Analyst
  • Incident Responders/Commanders
  • Digital Forensics Experts
  • Detection Engineers
  • Security Architects/Program Manager/DevOps Engineers

Types of Security Operation Center (SOC)

Fully Outsourced SOC: Hiring, Building, and retaining SOC Teams are challenging and expensive. There are not a lot of experienced Cyber Security Analyst and Engineers out there in the market. It’s honestly a new career option. To avoid the hassle, the organization often decide to outsource the security operation fully to Managed Security Service Providers (MSSP).

There are a few advantages and disadvantages of having a fully outsourced SOC. The most significant benefit is the speed; you can have someone start looking at your data/alerts as soon as you sign the contract.In there is any anamoly, MSSP will do the hunt, investigation and escalated it to you pretty quickly.

​The biggest downside is the knowledge gap. All the knowledge/intelligence about your network/endpoint stays with the MSSP. As soon as you cancel the contract, it’s gone. Another significant disadvantage is the MSSP is expensive. You have to pay a lot of money out of your budget  for the SOC. In some cases, the quality of the investigation can be poor too.  

Even after outsourcing your SOC, mitigating a malicious and compliance stays with the organization only. Usually, companies in the early stage will go for this model. MSSP will care more about the SLA’s rather that the quality of the investigation. If you are adopting this model, please ensure to discuss all the norms upfront, including the resume/profiles fo the Analysts.

Hybrid SOC: It’s a combination of the MSSP + In-house SOC team. Usually, the Detection, response, and forensics team will be in-house, and the Tier-1 & 2 Analyst will outsource. The majority of the pros and cons of MSSP mentioned above applies here as well. The benefit is you keep your institutional knowledge. If your want to run your SOC 24/7 and your security team is only in one country this model will be helpful in terms of coverage and control.

In-house SOC: Fully In-house SOC Teams are high, usually big size organizations with big budgets will go for this model. I’d say having a functional in-house SOC is a sign of maturity of an overall cybersecurity program. If your company is global, you may want to have your SOC team in mutiple time zones.

Key Responsibilities of SOC


  • Implement, Manage, and Propose Security Tools: SIEM, EDR, SOAR are the primary tools SOC uses, but they responsible for proposing new security gaps and devices to the business as well. If an alert/incident has made to the SIEM application, it must have bypassed specific security controls. SOC Analysts should always think about solutions to reduce the number of alerts/cases. A typical example is proposing an email security tool for reducing the number of phishing alerts.
  • Investigate, Respond, Contain, and Remediate Suspicious alerts: The core function of the SOC is to investigate the malicious activity. SOC cannot wholly rely on preventive and detective controls. A successful SOC is always on a Hunt.
  • Cyber Security Strategy: SOC is responsible for the overall Cyber Security strategy of the company. SOC should develop playbooks, SOP’s, Policies to respond to certain types of alerts. For example, SOC should develop a Cyber Security Incident Response Plan, Escalating the polity of HR/Legal, etc.
