Three Essential Measures for Your IT Security

Environments are growing increasingly complex – meaning greater security challenges for IT teams. The following tips can significantly improve your overall security posture.

Many companies are already prepared to allocate the necessary budgets and time for IT security. Yet despite their best efforts, IT leaders and security professionals remain overwhelmed – and cyberattacks continue to rain down on organizations.

Admittedly, maintaining precisely the right IT security safeguards for your own systems is no easy task. Vendor-provided documentation rarely covers all vulnerabilities or enables accurate threat forecasting.

To help strengthen your security across diverse environments, we’ve compiled three actionable recommendations for IT leaders and DevOps teams.

Develop an Incident Response Plan

People and processes are never perfect – we make mistakes. That’s why even well-protected organizations experience security incidents. A robust Incident Response Plan (IRP) is one of the most effective ways to stay ahead of those inevitable errors.

With a tested IRP in place, business operations need never be interrupted – and customers and employees remain confident and reassured. Crucially, response procedures must be rigorously exercised on a regular basis.

Independent third-party providers can conduct so-called “white-hat” penetration tests, simulating the latest threat techniques. These tests are performed unannounced to replicate real-world conditions as closely as possible – revealing whether security teams are truly prepared to respond to an actual attack.

Know Every Entry Point Across Your IT Inventory

Attackers have it easiest when they find unlocked doors into your environment. Gaining access becomes especially simple when the organization itself isn’t even aware that such a door exists.

Entry points into your data center may include shadow-IT servers, unmonitored applications or virtual machines – even entire applications long forgotten and left dormant.

Once attackers breach your perimeter, critical systems become effectively unprotected.

The solution: IT teams must maintain a continuously updated inventory system. It is essential to catalog all system and software assets – and prioritize them according to their business-criticality. Only then can appropriate security controls be applied where they matter most.

Update and Scan Your Systems Regularly

An unapplied security update has repeatedly been the root cause of exploited vulnerabilities – and thus of full-blown security incidents. The guiding principle is clear: unless an update demonstrably causes major operational issues, every effort should be made to keep all systems consistently up to date. Additionally, security scans should be run regularly across systems to detect open interfaces or other vulnerabilities.

Both practices – updating and scanning – must be performed routinely to ensure uninterrupted service for all users and proactively mitigate security risks.

Damage volume: Cybercrime causes over €8 trillion in global damages annually.

Skills shortage: More than 3.5 million cybersecurity professionals are missing worldwide.

Frequently Asked Questions

What are the most common cyber threats facing businesses?

According to the BSI (Federal Office for Information Security) Situation Report, ransomware, phishing, DDoS attacks, and supply-chain compromises rank among the most frequent threats. For German companies, regulatory risks – including the GDPR and NIS2 Directive – add further pressure.

How much should a company invest in cybersecurity?

Industry experts recommend allocating 10-15 percent of the total IT budget to cybersecurity. According to Bitkom, German companies average 14 percent. What matters most isn’t just the amount – but how strategically it’s distributed across prevention, detection, and response capabilities.

Does every company need a Chief Information Security Officer (CISO)?

Not every organization requires a full-time CISO – but every company does need clearly defined, board-level accountability for IT security. SMEs can engage an external CISO (a “Virtual CISO”) to fulfill this role. Under NIS2, management-level responsibility for cybersecurity is now legally mandated.
