Cyberattacks don’t happen by chance; they are often the result of careful planning and precise execution. The first step in this process is reconnaissance, where attackers gather information about their target. This stage is crucial as it sets the foundation for the entire attack. By identifying vulnerabilities, understanding infrastructure layouts, and profiling employees, attackers craft a customised plan to exploit the organisation. In the Cyber Kill Chain, reconnaissance represents the first opportunity for defenders to disrupt the attack, and Syscomm’s defence in depth strategy is designed to do exactly that.

During reconnaissance, attackers use techniques such as scanning networks, searching for publicly available information, and conducting social engineering. Open-source intelligence (OSINT) tools can reveal exposed IP addresses, unpatched software, or misconfigured systems. Similarly, phishing attempts or pretexting strategies aim to extract sensitive information from employees. The goal of the attacker is to build a complete picture of the target’s vulnerabilities. If left undetected, this phase can leave organisations exposed to precisely targeted attacks that bypass traditional defences.

Syscomm addresses this critical stage with a proactive approach that combines visibility, detection, and mitigation. The first layer of defence is Attack Surface Management (ASM), which continuously monitors an organisation’s external-facing assets. ASM helps identify and close gaps such as unpatched systems, publicly accessible ports, or misconfigured applications that attackers might exploit. By continuously reducing the attack surface, Syscomm makes it significantly harder for attackers to gather actionable intelligence.

Another key component of Syscomm’s strategy is Threat Intelligence. By leveraging insights into known attack methods, emerging vulnerabilities, and industry-specific risks, Syscomm helps customers stay one step ahead of attackers. Threat intelligence feeds are integrated into tools like Security Information and Event Management (SIEM) systems, enabling real-time detection of suspicious activities such as unauthorised scans or repeated login attempts. This ensures that reconnaissance efforts are identified and blocked early, before attackers can proceed to the next phase.

Syscomm also employs penetration testing and vulnerability management to simulate the reconnaissance phase from an attacker’s perspective. By identifying and addressing weaknesses through ethical hacking and regular scans, Syscomm ensures organisations are prepared for real-world threats. These tests mimic the tactics, techniques, and procedures (TTPs) used by attackers, providing actionable insights into where defences need to be strengthened.

However, reconnaissance isn’t limited to technology. Attackers often target people, recognising that employees can unintentionally provide critical information. To counter this, Syscomm prioritises security awareness training. By educating staff on phishing, social engineering, and suspicious behaviour, organisations can significantly reduce the likelihood of employees falling victim to reconnaissance efforts. Regular training sessions, combined with simulated phishing campaigns, help reinforce a culture of vigilance and empower employees to become the first line of defence.

In addition to training, Syscomm uses data classification and governance policies to ensure sensitive information is managed securely. This includes limiting access to critical data, encrypting communications, and applying data loss prevention (DLP) technologies to monitor and control how information is shared. By securing organisational data and enforcing strict access controls, Syscomm makes it more difficult for attackers to obtain valuable intelligence during the reconnaissance phase.

A key differentiator in Syscomm’s approach is the integration of event visibility. Through solutions like network traffic monitoring and behaviour analytics, Syscomm helps organisations detect and respond to unusual patterns indicative of reconnaissance activity. For example, a sudden increase in network scans or repeated failed login attempts may signal an attacker probing the defences. These insights enable organisations to respond swiftly, whether by blocking IP addresses, adjusting firewall rules, or initiating incident response protocols.

Syscomm’s defence in depth strategy during reconnaissance exemplifies the importance of layering both technical and human defences. By combining advanced technologies with proactive monitoring and a focus on employee awareness, Syscomm ensures organisations are equipped to detect and disrupt reconnaissance attempts. This not only prevents attackers from gathering the information they need but also sends a clear signal that the organisation is prepared and resilient, potentially deterring future attempts.

The reconnaissance stage is often overlooked because it occurs before any visible damage is done, but it is arguably one of the most critical phases of an attack. If attackers are thwarted during this phase, the entire attack can be neutralised before it begins. Syscomm’s expertise in addressing reconnaissance through attack surface management, threat intelligence, penetration testing, and user training ensures that customers have a strong, proactive defence. By stopping attackers early, organisations can focus on their operations without fear of unseen threats.

As we continue this blog series, we’ll explore how Syscomm’s defence in depth approach tackles the subsequent stages of the Cyber Kill Chain. The next phase is weaponisation, where attackers transform the intelligence gathered during reconnaissance into malicious tools. With Syscomm’s layered strategy, every step of the Kill Chain becomes a chance to disrupt and protect.
