SaaS Alerts highlights MSP cybersecurity: Emerging threats & best practices

For an MSP with a wide range of clients, they not only have to secure multiple endpoints, networks and cloud environments, but also put up a strong wall against an increasingly sophisticated threat landscape.

Let’s explore the latest security threats and MSP best practices to boost MSPs — and their clients’ — cyber resilience.

Emerging threats in cybersecurity for MSPs

MSPs are up against a constantly changing threat landscape to protect diverse customer setups.

The top emerging security threats for MSPs to be aware of include:

• Supply chain attacks - Threats originating in the supply chain compromise the integrity of software, hardware or services that MSPs deliver to their clients.
• Ransomware as a service (RaaS) - The pre-configured infrastructure of RaaS makes it easier for attackers to launch ransomware campaigns, increasing the risk of disruption of services and financial losses for both MSPs and their clients.
• Zero-day exploits - These attacks target a previously unidentified security flaw. If not addressed promptly, zero-day exploits lead to unauthorised access, data breaches and potential widespread damage.
• Advanced persistent threats (APTs) - These are sophisticated, long-term attacks aimed at obtaining valuable information from specific organisations, industries or entities. APTs result in persistent unauthorised access, data exfiltration and compromise of critical systems.
• Credential stuffing - Attackers take advantage of the fact that many people reuse their credentials. After stealing a username and password, criminals use the information to compromise accounts on other sites.
• Fileless malware - These attacks evade traditional antivirus detection, making it challenging to detect and mitigate. Fileless malware leads to stealthy and undetected compromises and data theft.
• DDoS attacks - Attackers use multiple compromised systems to flood a target system, service or network with a massive volume of traffic. DDoS attacks result in temporary or extended periods of service downtime.
• Business email compromise (BEC) - BEC involves email-based attacks that target business processes and financial transactions. Successful BEC attacks result in financial fraud, unauthorised fund transfers and compromise of sensitive business information.

10 cybersecurity best practices for MSPs

As the clients continue to grow, there is a corresponding increase in the number of endpoints

As the clients continue to grow, there is a corresponding increase in the number of endpoints, networks and cloud environments that create a larger attack surface to guard.

This growth also amplifies the need for standardised MSP best practices to secure all their clients, regardless of size, complexity or uniqueness.

Let’s look at the top ten best practices of cybersecurity for MSPs:

• 1. Understand the clients’ security needs

Each client has unique business operations, industry-specific challenges and regulatory compliance requirements. By understanding these specific needs, MSPs can tailor their security solutions to address each client’s distinct vulnerabilities and threats. This way, they can prevent unnecessary spending on generic solutions that may not fully address the client’s unique risks.

• 2. Conduct periodic risk assessments

Regular SaaS security risk assessments help identify potential vulnerabilities and threats within the clients’ environments. These assessments analyse a wide range of risks, including data security, access controls, compliance with regulatory standards and the overall resilience of SaaS platforms. With this proactive approach, clients can mitigate risks before they can be exploited.

• 3. Monitor and detect threats

Proactive threat monitoring and detection involves the continuous surveillance of network and system activities, in order to identify and respond to potential security incidents.

MSPs can configure internal tools to generate automated alerts for potential security incidents

Using user behavioural analysis, such as unusual login locations, access patterns or data transfer volumes, MSPs can identify deviations from normal user activities and system behaviour, spotting possible breaches before they can lead to data loss.

By deploying SaaS security software like SaaS Alerts, MSPs can configure internal tools to generate automated alerts for potential security incidents or even set up automation rules to immediately lock down accounts, when a breach is suspected. Alerts can be prioritised based on severity to reduce alert fatigue.

• 4. Establish clear security roles and responsibilities

Clearly delineating who is responsible for what aspects of security makes it easier to manage, monitor and respond to potential threats. Establishing distinct security roles and responsibilities internally ensures that all facets of the clients’ infrastructure, data and operations are protected against potential threats.

• 5. Implement IAM policies

MSPs should implement strong identity access management (IAM) policies in their clients’ network to ensure only authorised individuals can access specific company resources. It involves secure authentication, least privilege principles and continuous monitoring of user access.

• 6. Segment client networks

Network segmentation involves dividing a network into segments to limit the lateral movement of bad actors in the event of a security breach. With this strategy, MSPs isolate each client’s network, preventing unauthorised access in the event of a security incident affecting one client.

Going a step further, MSPs can also implement micro-segmentation to isolate individual devices or applications of each client.

• 7. Execute data loss prevention policies

For MSPs managing cloud environments, consider leveraging cloud-based security measures

Employ a comprehensive data loss prevention (DLP) strategy to mitigate the financial and operational risks of data loss.

Effective DLP involves using data discovery and classification tools to automatically identify sensitive data across the network, even in unstructured data.

For MSPs managing cloud environments, consider leveraging cloud-based security measures, such as Office 365 Data Loss Prevention. These solutions monitor and protect data across cloud platforms, ensuring consistent security policies.

• 8. Implement data backup strategies

Establishing robust data backup and recovery strategies mitigates the impact of data loss due to cyber incidents, hardware failures or other disasters. Conduct regular backups of critical data, including databases, files and configurations. The frequency of backups should align with the data’s criticality and the rate of change.

MSPs can also configure security alerts to notify administrators of any failures or abnormalities in the backup process, enabling prompt corrective action.

• 9. Train employees

Human error is the most common reason behind cybersecurity incidents. In fact, 74% of data breaches involve a human element through social engineering attacks, errors or privilege misuse, according to Verizon.

MSPs should provide comprehensive training programmes catered to their clients’ employees to increase awareness of cybersecurity best practices, such as recognising phishing attempts and following secure procedures to protect client data.

• 10. Develop an incident response plan

An incident response plan outlines the procedures and actions that the MSP will take in the event of a cybersecurity incident. A well-prepared plan helps in identifying the attack, isolating systems and mitigating the risks. Early detection and containment measures outlined in the plan can prevent a minor incident from turning into a widespread security breach.
