In these times, Chief Information Security Officers (CISOs) mMust implement strategies that enable the real- time monitoring of cyber security threats in order to prevent data breaches.

Continuous security monitoring is a highly effective and emerging strategy that allows organizations to monitor their entire IT infrastructure for compliance and risk management purposes, providing a valuable bird’s eye view that can aid in identifying potential issues before they manifest as security threats. It is vital to understand continuous security monitoring as a framework because it not only allows organizations to track changes in the IT environment but also helps to uncover potential configuration errors or unauthorized changes, thus enabling the implementation of necessary remediating actions.

This article helps you define what continuous security monitoring exactly is and understand whether your organization requires it. The article also discusses the different types of continuous security monitoring that are implemented across the industry, and how to effectively implement continuous security monitoring in a way that is best suited to your organization’s requirements. Read on to know more!

What is Continuous Security Monitoring?

Continuous security monitoring (CSM) is an automated approach that provides ongoing surveillance of an organization's IT infrastructure to identify vulnerabilities and threats in real-time. This proactive strategy is crucial for maintaining compliance with security standards and protecting sensitive data from breaches. By continuously monitoring security controls and assessing the risk landscape, organizations can respond promptly to emerging threats, ensuring the confidentiality, integrity, and availability of their systems and data.

An effective continuous security monitoring system provides robust support to organizational risk management decisions by providing real time visibility of indicators of compromise, vulnerabilities in organizational infrastructure and networks, and misconfigurations of security controls.

A continuous security monitoring solution is the answer to your problem if you need help to monitor the following prevalent security risks:

• Unnecessary ports, which can be dangerous when the service listening in on the port is misconfigured, or has poor network and security rules, or is vulnerable to exploitation. Wormable ports in particular are a security risk because they are open by default on some operating systems.
• A lack of Sender Policy Framework (SPF), DomainKeys Identified Mail  (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC), which can make your system vulnerable to email security breaches.
• Domain hijacking, where the registration of a domain name can be changed without the permission of its original owner. This is especially concerning. If you don't subscribe to Internet Engineering Task Force (IETF) specifications like the Domain Name System Security Extensions (DNSSEC or DNS security extensions), which are imperative to securing DNS information on IP networks.
• Typosquatted domains, where similar domain names are bought out by the attacker to target users who incorrectly type in the website address of the company or brand they want to look up. 
• Data leaks and other vulnerabilities, including vulnerability to XSS (cross-site scripting) attacks.
• Man-in-the-middle attacks (MITM), which can obscure business communication.

How Does Continuous Security Monitoring Work?

Typically, CSM works as an ongoing monitoring system that consistently surveys for security vulnerabilities and monitors security controls to ensure that an organization's systems and data are protected. It is a tool or process that you can set up to identify vulnerabilities before they result in a serious security breach.

The automated nature of continuous security monitoring ensures that you are alerted of potential threats in a timely manner so that your organization's risk management policies stay relevant and functional.

In line with NIST guidelines, continuous security marketing works by:

• Maintaining complete awareness of all systems across the organization and its vendor ecosystem,
• Having a detailed understanding of security threats and ongoing threat activities,
• Having access to, and assessing all security controls,
• Collecting, correlating, and analyzing security related information,
• Providing actionable feedback regarding the organization’s security status across all cross-functional teams and tiers,
• Evolving and active management of security risk by personal, and
• Integrating IT security with risk management framework.

In order to fulfill all of the above roles, a good continuous monitoring program must collect information in line with industry standard metrics, and utilize data available through your organization’s security controls paired with automated scanning.

What Does Continuous Security Monitoring Do?

Sense vulnerabilities can emerge at any time, CSM of your organization’s entire network aids in their quick detection and remediation. In a nutshell, continuous security monitoring is a crucial process for all stakeholders involved in an organization's IT security infrastructure, including suppliers and vendors.

Continuous security monitoring has various important roles in an organization. Its main responsibilities include:

1. Real time visibility

Continuous security monitoring is responsible for providing ongoing insight into the organization's IT environment, including an up-to-date report of all assets, their current status, and possible vulnerabilities. This feature of real time visibility is key to the swift detection of any discrepancies or security breaches.

2. Automated scans and assessments

Continuous security monitoring automatically scans and evaluates security systems on a regular basis. This eases the usually cumbersome process of manual system assessment which is not possible to be implemented regularly.

3. Threat intelligence integration

A holistic continuous security monitoring solution often works alongside global threat intelligence fields. This enables CSM to compare an organization’s internal security environment with the latest global threat data and make sure that your business is shielded from the newest cyber threats.

4. Proactive approach

The ‘continuous’ in continuous security monitoring is responsible for the organization's potential transition from practicing a reactive security stance to a more proactive approach. Effective CSM allows you to foresee potential cyber threats and address them even before breaches occur, so your security team does not have to wait around until your organization is compromised.

5. Streamlined compliance

CSM assists organizations in maintaining continuous compliance with industry standards. This is especially useful as regulations and audits concerning data protection and security become more stringent as technology progresses. Continuous security monitoring can automatically register deviations from acceptable compliance benchmarks and notify your organization about the same so that you remain within regulatory boundaries.

6. Integrated incident response

Continuous security monitoring is also responsible for triggering immediate automated or semi automated responses in the event of a security incident. In the event of a breach, CSM can perform actions such as

• Isolating affected systems,
• Notify appropriate personnel, or even
• Initiating pre-set mitigation and remediation strategies.

The integrated nature of CSM response to security threats ensures that every organizational tier is Informed and up-to-date about the company’s security status. This can greatly diminish response time on a macro level.

7. Enhanced decision making

Since CSM provides key decision makers with continuous and updated data about the organization's security posture, it is crucial to the quick and timely implementation of strategies that key decision makers arrive at in response to this information. By enabling informed and relevant decision making and precise action, CSM allows you to form a highly effective and holistic security framework.

Now that you are aware of the detailed functionality of a working CSM approach, let us examine the different types of continuous security monitoring approaches that organizations implement across the industry.

What are the Main Types of Continuous Security Monitoring?

There are three main types of continuous security monitoring. They are:

1. Infrastructure Monitoring

Infrastructure monitoring monitors the physical components of a security system, including servers, storage, and networking equipment. It can be used to identify tangible problems regarding hardware, malfunction, or the working of other physical components in your organizational security system. When your security team flags a hardware or motherboard issue due to physical symptoms like overheating, it is a result of infrastructure monitoring.

2. Application Monitoring

In contrast to infrastructure marketing, application monitoring is responsible for the software components of your security system, including everything to do with your application codes, online server, and digital database. With the help of application monitoring, your security team can pinpoint issues such as slow performance, memory leaks or even a suspicious modification in your application code that can prove to be malicious.

3. Network Monitoring

Network monitoring, keep tabs on your network traffic, including your organization’s router, switches, and other networking equipment. It is useful in identifying network issues such as packet loss or high latency.

Depending on your organization's needs, you can use one, all, or even a combination of the above types of security monitoring for the best results. If you still need convincing about the need for a continuous security monitoring framework, read on for a reminder of the benefits it can offer!

Benefits of Continuous Security Monitoring 

Continuous security monitoring represents a major shift in the world of corporate security. Due to its key feature of providing real time visibility into IT security data, continuous security monitoring provides a range of benefits such as:

• A holistic understanding of your organization's risk tolerance, which allows you to set the right priorities and manage both internal and external risk consistently across all tiers of the organization.
• A detailed understanding of your organization’s security status, substantiated by relevant cyber security metrics that are in line with industry standards and regulations.
• Increased effectiveness of security controls as a result of having in depth information at your fingertips.
• Visibility of all your organization’s IT assets simultaneously, which can help streamline your security endeavors.
• Affirmation of your organization, compliance with information security policies in a systematic way that is legally verifiable. CSM allows you to ensure that your organization adheres to not only federal legislation, directives, regulations, standards, guidelines, policies, and best practices, but also to organizational missions and business functions.
• Unobstructed access to changes, updates, knowledge of, and control over security systems and environments.
• Reduced cyber security risk, reduced impact of successful cyber attacks, and reduced cost of data breaches across all organizational tiers.
• Protection of all your digital assets and sensitive data such as PII, PHI, and trade secrets against external attacks, insider attacks, and even supply chain or third party ecosystem attacks. In fact, a robust CSM also extends this protection to digital assets owned and operated by third party vendors, like cloud providers, SaaS and IaaS, business partners, suppliers, or external contractors.

How Can Organizations Effectively Implement CSM?

To understand how organizations effectively implement CSM, it is important to remember that continuous security monitoring provides security professionals with real time visibility into an organization's attack surface. The attack surface refers to the total number of attack vectors that can be utilized at any moment to launch a successful cyber attack against an organization's security defenses. This event can cause data loss or grant the attacker access to sensitive data.

In order to minimize their attack surface, organizations rely on timely, accurate, and relevant data to limit the resources under threat and prioritize security efforts effectively. This is also why organizations give security ratings to their vendors to simplify the process of CSM and improve organizational security. Let's take a brief detour and explore what security ratings are, and why they enhance your CSM strategy.

Security Ratings: Why Are They Essential? 

Security ratings are key to effectively adopting CSM as a strategy. With validated security readings, security professionals can continue their ongoing assessment and updating of their business processes, core mission, security needs, and internal governance structure. Security ratings are data driven, objective, and dynamic measurements of an organization’s security posture and have proven to be valuable as an objective indicator of any organization’s security performance and infrastructure.

Security ratings greatly minimize an organization's tax surface and are the most popular method of continuous security monitoring and vendor risk management. Security ratings can help your organization:

• Continually access important IT security data and thugs assess threats to internal security with the help of a simple and easy to implement rating, which can be useful for explaining security protocols to important but non technical decision makers and stakeholders within the organization, such as C-suite members, board members, and regulators.
• Provide informed assurance to customers, regulators, insurers, and any involved stakeholders that keeping their data secure is your highest priority. Security ratings are a clear indicator that an organization prioritizes the prevention of privacy issues like malware, ransomware, and data breaches.
• Get a clear idea of industry benchmarks and be able to compare industry competitors, peers, and vendors objectively. This in turn speeds up the process of decision making and helps you identify mitigation and remediation strategies that the organization needs to invest in.
• Gain an in depth understanding of third party risk, fourth party risk, and even N-th party risk posed by multiple sources, such as third party vendors, business partner relationships, and even the supply chain.

Now that you're aware of the importance of security ratings, let's examine what the successful adoption of CSM tools looks like. 

Good security monitoring tools such as Cyber Sierra account for all software, SaaS, cloud, and hardware assets that an organization has and assign them categories based on how critical they are to your organization's business. Not only can these tools, alert you of possible cyber security threats, but they also help to list the following:

• Known and Unknown assets

Known assets are inventoried And managed assets including But not limited to your organizations, corporate website, servers, and any other applications or services that depend on the servers for their functionality. 

Meanwhile, unknown assets refer to orphaned IT or shadow IT infrastructures, which are constructed outside of the established domain of your internal security team. This could refer to development or marketing websites that are no longer on your radar but can still be linked to your organization.

• Rogue assets

Rogue assets refer to malware, typo squatted domains, domain impersonating websites or mobile applications, and other malicious infrastructure put in place by attackers and security threat actors.

• Vendors

Vendors are the source of a major proportion of third party risk and fourth party risk. They are an important part of your attack surface and must be accounted for. A good CSM helps you list vendors, regardless of their size or importance. Furthermore, an effective CSM can categorize vendors by their risk and criticality, which is essential in a technological landscape where even the smallest of vendors can introduce a large risk into your security framework.

Below is a brief checklist that you can refer to before committing to a CSM tool:

• Ensure that all your digital assets are covered.
• Ensure that whichever continuous monitoring tool you pick integrates with your organization's interface and infrastructure and can adapt to new security frameworks as you introduce or modify them. Ideally, a good CSM should classify security infrastructure as it processes information regarding internal ownership, vendor data, and operating systems.
• Make sure that you have an internal action protocol in place in case of vulnerability detection.
• Keep your organization's data ready to sync with automated software.
