Cyber Defense Services | SITS
Security Operations Services: 24/7 Security

Companies must protect themselves against numerous new forms of attack – and in some cases in completely new sectors: Hybrid working models and the countless cloud services are preferred targets for hackers. And the the shortage of qualified IT specialists additionally has made defense more challenging.

The solution are cyber defense teams. These special units are formed from in-house or external security experts. With an arsenal of modern security solutions, they fight cyber threats around the clock. They prevent security incidents, respond to acute threats and restore the company’s IT in the event of successful attacks.

What is a Cyber Defense Service?
A Cyber Defense Service ensures continuous monitoring and defense against cyber threats for companies. The core components include Cyber Threat Intelligence, Incident Response, Security Monitoring, Vulnerability Management and Security Automation & Orchestration. Here is the most important information about Cyber Defense Services.

Looming threats, insufficient resources

Prevent attacks 24/7 and respond before it’s too late

According to statistics, it takes an average of 207 days for new cyber threats to be identified and 73 days for them to be completely resolved. Companies must therefore be prepared for threats 24 hours a day to avoid falling victim to attacks.

Five key cyber challenges
In the fight against modern threats, security software alone is far from sufficient. The situation has drastically evolved in recent years and companies are facing major challenges.

1. Data overload & alerts
IT and security managers are often overwhelmed by the thousands of warning messages from networks, devices and services.

  • The most important things are often difficult to identify: The many alerts from devices such as smartphones, PCs, IoT devices and cloud services make it difficult to identify real threats.
  • Individual solutions are not enough: even a SIEM cannot always filter security-relevant data sufficiently.

2. Complex structures
The ``Work from Anywhere`` environment poses numerous security challenges. The main challenges:

  • Incomplete monitoring and identification: Globally distributed systems and services are more difficult to secure - there are too many weak links in the IT chain.
  • Delayed response times: These occur frequently with complex IT structures.
  • New threats from BYOD, IoT and OT: Attackers are focusing on new or private devices that are often not adequately protected.

3. Fragmented security systems and ``blind spots``
Firewalls, SIEM, malware protection: ensuring security with individual solutions is complex and challenging. The risks:

  • Fragmented IT: Long response times due to individual analysis of alerts from devices, networks or cloud services
  • High costs: escalating costs due to individual, constantly adapted solutions and providers

4. Fighting the unknown
Companies need to be fully informed about current threats. The challenges:

  • Advanced Persistent Threats (APT): Sophisticated attackers hide undetected in the network, steal data and cause long-term damage.
  • Phishing: Employees easily fall victim to scams as phishing attacks become increasingly sophisticated.
  • Zero-day vulnerabilities: Previously unknown or unpatched vulnerabilities are bringing IT structures to a standstill.

5. Worst case scenario: shutdown of the entire IT system
A cyber attack can completely shut down a company's entire IT system. This means:

  • Work and production standstill due to interrupted systems and restricted communication
  • Reputational damage due to operational downtime or data loss - with financial consequences

The five key elements
A good security operations unit includes the following core areas:

1. SIEM - Data in the center of security
Security Information Event Management (SIEM) ensures a clear data situation and is at the heart of every cyber defense solution. It offers:

  • Efficient data analysis: A SIEM collects security-relevant IT data and filters it according to threat level.
  • Continuous optimization: In view of the constantly changing threat situation, the SIEM must be continuously adapted.

2. Security Operations Center (SOC) - the 24/7 line of defense
The SOC is the control center for IT security. It uses the data analyzed by the SIEM and software-based approaches such as XDR. It offers:

  • 24/7 Detection & Response: Immediate response to complex threats
  • Comprehensive expertise and solid database: access to security experts and access to threat intelligence feeds
  • Strong IT governance: transparency through defined service level agreements (SLA), KPIs and consistent reporting

3. Managed XDR - identifying and Responding Across IT Boundaries
Extended protection and response services (Extended Detect and Response, XDR) ensure that the entire IT is protected. XDR offers:

  • 360-degree protection: Defense against threats to devices, networks, cloud infrastructures and applications
  • The entire IT at a glance: Monitoring of local and cloud resources

4. Cyber Threat Intelligence - current threat data at a glance
CTI solutions collect, analyze and interpret data on current and impending threats from various sources. The advantages:

  • Prompt warnings: The CTI warns of new vulnerabilities and attacks and helps defend against malware, phishing and other cyber attacks.
  • Network monitoring: A CTI also includes web monitoring, leak detection and VIP protection. It monitors the network for data leaks and identity theft.
  • Seamless integration: The CTI fits into the SIEM/SOC structure and provides it with up-to-date data.

5. Incident Response Services (CSIRT) - a security grid for emergencies
With a skilled incident response team, companies can rapidly respond to emergencies. The tasks of a CSIRT team:

  • Identifying and closing exploited security vulnerabilities
  • Further support, for example in cooperation with authorities and through security tests (pentesting)
  • Legal compliance and discretion: compliance with all data protection laws and protection of your reputation

Characteristics of good Cyber Defense Services
Good cyber defense services combine expertise, technology, defined processes and commitment. Expert teams and services such as CTI, XDR, SOC and CSIRT ensure security and efficient preparation and response to cyber attacks. This includes:
  • Proactive threat detection: Instead of just reacting to events, the Cyber Defense team proactively searches for potential threats using SIEM and CTI.
  • Fast response time: In the event of security incidents, a quick response is crucial to minimize the damage. Clearly defined escalation procedures and response plans (CSIRT) take effect immediately and stop threats.
  • 24/7 monitoring: Good cyber defense services offer continuous round-the-clock monitoring by a Security Operations Center (SOC) that identifies and responds to threats.
  • Integration of the latest technologies: Advanced security technologies such as SIEM, XDR, CTI and co. must be implemented seamlessly and the interaction of services must be guaranteed.
  • Specialized team: An experienced team of experts, including analysts, incident responders, threat hunters and security architecture specialists, is essential.
  • Customized solutions: Every organization has unique security requirements and risks. Good cyber defense services therefore offer customized solutions.
  • Reporting: The team provides transparency and timely action with reports on security incidents, detection and response performance, and recommendations.
  • Continuous improvement: Good cyber defense services are constantly learning - by analyzing security incidents and trends, implementing lessons learned and adapting new processes and technologies.

Such complex interaction can hardly be managed with internal resources. This is why companies often rely on a well-established team of service providers (``managed service providers``).
