When is the right time for vulnerability scanning?
All it takes for cybercriminals to breach your mission-critical networks, database, and IT systems is a single unpatched vulnerability. To prevent this and maintain good cyber hygiene, you need to obtain real-time vulnerability data.
Vulnerability scans generate a lot of data that when analyzed reveal several security flaws. Given the time and resources required to fully scan modern IT infrastructures, many organizations (especially those with a large number of digital assets and complex networks) may opt to execute vulnerability scans when they have the capacity to deal with the resultant data. This could be once a month or every quarter.
However, new vulnerabilities emerge almost every day due to the rapidly evolving nature of the threat landscape. If the gap between periodic scans is too long, malicious actors can take advantage of undetected vulnerabilities in your system and launch a range of cyber attacks. To safeguard your IT ecosystem, you need to perform vulnerability scanning at the right time.
Continuous scanning
Since vulnerabilities can crop up from any digital asset at any time, scanning your IT infrastructure on a continuous basis is the most effective approach to vulnerability management. However, continuous scanning can create several problems. Continuous scanning can:
- Affect the speed of the systems, applications, and networks being scanned
- Produce a constant barrage of alerts and triggers which could lead to alert fatigue
- Generate a large number of false positives which drain time and resources
Since these cons outweigh the benefits of continuously executing vulnerability scans, let's take a look at factors that will help you decide the right time for vulnerability scanning.
Compliance standards
Since many compliance standards such as HIPAA, PCI DSS, GDPR, and others explicitly state security scanning frequency, some organizations execute vulnerability scans based on the regulatory frameworks their industry and business operations are subject to.
For instance, PCI DSS requires organizations that handle data related to credit card transactions in the payments industry to run scans every quarter. However, choosing the frequency of vulnerability scanning based entirely on compliance requirements isn't advisable since regulatory frameworks provide a one-size-fits-all guideline that may not be suitable for your business.
As such, using these standards to determine the right time for vulnerability scanning may not be ideal for your use case. And doing so may increase your security risks due to the evolving nature of the cybersecurity landscape. If you're looking to actually secure your digital assets (and not simply tick a box for compliance purposes), it's best to go above and beyond the regulations stipulated in your industry's regulatory frameworks.
Infrastructural changes
While some businesses may have a somewhat static IT environment, most modern organizations such as tech startups, and companies that operate at the forefront of cutting-edge technology continuously make rapid changes to their IT applications, systems, and architecture. These companies continuously make frequent changes to their codebase multiple times a day, deploy new IT assets, decommission existing ones and continuously reconfigure/expand their networks. All these rapid changes create the potential for a slew of security gaps and misconfigurations that could lead to the emergence of security vulnerabilities.
To mitigate the prevalence of these security gaps, you should always conduct vulnerability scans after making changes to your IT infrastructure, and digital assets. Running continuous vulnerability scans is essential to the security of rapidly evolving IT assets such as cloud infrastructure (Google Cloud, Azure, and AWS) where resources can be provisioned and decommissioned every few minutes.
How to determine the right time to perform a vulnerability scan
Effective vulnerability management isn't a periodic or one-time project. In today's fast-paced cyber environment where ransomware attacks occur once every 11 seconds, monthly or quarterly vulnerability scans aren't enough to safeguard your IT ecosystem and prevent security breaches. Whether it's your firewall, VPN, development framework used by engineering teams, operating systems, web servers, or cloud infrastructure, all these assets can develop new vulnerabilities at any time, even when there are no new deployments or configuration changes.
The continuous assessment of your organization's digital assets, servers, connectivity, and applications enables your security team to stay on top of emerging cyber threats and security gaps within your network. However, this doesn't mean that you should run vulnerability scans around the clock.
Cybersecurity experts recognize the effectiveness of continuous vulnerability scanning and monitoring in protecting digital assets from security threats. As such, they recommend performing vulnerability scans once daily. But to determine if this is the best for your unique use case, you should first define your risk appetite and understand the value of every asset and network device that makes up your digital ecosystem.
Understanding the criticality of an attack on these assets can help you determine how frequently you should execute your vulnerability assessment process. Depending on the complexity of your infrastructure and the severity of the identified vulnerability gaps, it may take a couple of days to properly detect, resolve, and remediate all issues. In such environments, vulnerability scanning should be performed at least twice a week. Always do a follow-up scan after applying the security fixes and patches to ensure the total resolution of previously detected vulnerabilities
Using automated scanning tools
Although it is easier for organizations with few digital assets and a simple network to conduct biweekly scans, doing so may not be necessary due to the static nature of such IT environments. Conversely, daily scans can help detect vulnerabilities lurking in large networks, complex IT ecosystems, and rapidly changing infrastructures. However, the sheer volume of these assets makes this a challenging and resource-intensive undertaking. In such cases, it's best to deploy an intelligent, automated scanning tool that passively scans your growing IT infrastructure and proactively scans new additions or changes to your network.
Maintain cybersecurity
To attain and maintain good cyber hygiene, you need to obtain real-time vulnerability data. Combining daily scanning with continuous monitoring can help you gain 360-degree visibility into your IT ecosystem and provide real-time vulnerability data without fatigue alert.
While most compliance frameworks require you to use third-party vulnerability scanners like Snyk or AWS Inspector to scan your IT environment, a robust compliance platform like Vanta enables you to do so much more.
Determine if you need to comply with GDPR
Not all organizations are legally required to comply with the GDPR, so it’s important to know how this law applies to your organization. Consider the following:
Do you sell goods or services in the EU or UK?
Do you sell goods or services to EU businesses, consumers, or both?
Do you have employees in the EU or UK?
Do persons from the EU or UK visit your website?
Do you monitor the behavior of persons within the EU?
Document the personal data you process
Because GDPR hinges on the data you collect from consumers and what your business does with that data, you’ll need to get a complete picture of the personal data you’re collecting, processing, or otherwise interacting with. Follow these items to scope out your data practices:
Identify and document every system (i.e. database, application, or vendor) that stores or processes EU- or UK-based personally identifiable information (PII).
Document the retention periods for PII in each system.
Determine whether you collect, store, or process “special categories” of data, including:
Determine whether your documentation meets the GDPR requirements for Records of Processing Activities, that include information on:
Determine whether your documentation includes the following information about processing activities carried out by vendors on your behalf:
Determine your legal grounds for processing data
GDPR establishes conditions that must be met before you can legally collect or process personal data. Make sure your organization is meeting the conditions listed below:
For each category of data and system/application, determine the lawful basis for processing based on one of the following conditions:
Review and update current customer and vendor contracts
For your organization to be fully GDPR compliant, the vendors you use must also maintain the privacy rights of your users’ and those rights should be reflected in your contracts with customers:
Review all customer and in-scope vendor contracts to determine that they have appropriate contract language (i.e. Data Protection Addendums with Standard Contractual Clauses).
Determine if you need a Data Protection Impact Assessment
A Data Protection Impact Assessment (DPIA) is an assessment to determine what risks may arise from your data processing and steps to take to minimize them. Not all organizations need a DPIA, the following items will help you determine if you do:
Identify if your data processing is likely to create high risk to the rights and freedoms of natural persons. Considering if your processing involves any of the following:
Clearly communicate privacy and marketing consent practices
A fundamental element of GDPR compliance is informing consumers of their data privacy rights and requesting consent to collect or process their data. Ensure your website features the following:
A public-facing privacy policy which covers the use of all your products, services, and websites.
Notice to the data subject that include the essential details listed in GDPR Article 13.
Have a clear process for persons to change or withdraw consent.
Update internal privacy policies
Ensure that you have privacy policies that are up to the standards of GDPR:
Update internal privacy notices for EU employees.
Have an employee privacy policy that governs the collection and use of EU and UK employee data.
Determine if you need a data protection officer (DPO) based on one of the following conditions:
Review compliance measures for external data transfers
Under GDPR, you’re responsible for protecting the data that you collect and if that data is transferred. Make your transfer process compliant by following these steps:
If you transfer, store, or process data outside the EU or UK, identify your legal basis for the data transfer. This is most likely covered by the standard contractual clauses.
Perform and document a transfer impact assessment (TIA).
Confirm you comply with additional data subject rights
Ensure you’re complying with the following data subject rights by considering the following questions:
Do you have a process for timely responding to requests for information, modifications, or deletion of PII?
Can you provide the subject information in a concise, transparent, intelligible, and easily accessible form, using clear and plain language?
Do you have a process for correcting or deleting data when requested?
Do you have an internal policy regarding a Compelled Disclosure from Law Enforcement?
Determine if you need an EU-based representative
Depending on how and where your organization is based, you may need a representative for your organization within the European Union. Take these steps to determine if this is necessary:
Determine whether an EU representative is needed. You may not need an EU-rep if the following conditions apply to your organization:
If the above conditions do not apply to you, appoint an EU-based representative.
Identify a lead data protection authority (DPA) if needed
GDPR compliance is supervised by the government of whatever EU member-state you’re operating in. If you’re operating in multiple member-states, you may need to determine who your lead data protection authority is:
Determine if you operate in more than one EU state.
If so, designate the supervisory authority of the main establishment to act as your DPA.
Implement employee training
Every employee in your organization provides a window for hackers to gain access to your systems and data. This is why it's important to train your employees on how to prevent security breaches and maintain data privacy:
Provide appropriate security awareness and privacy training to your staff.
Integrate data breach response requirements
GDPR requires you to create a plan for notifying users and minimizing the impact of a data breach. Examine your data breach response plan, by doing the following:
Create and implement an incident response plan which includes procedures for reporting a breach to EU and UK data subjects as well as appropriate data authorities.
Establish breach reporting policies that comply with all prescribed timelines and include all recipients (i.e. authorities, controllers, and data subjects).
Implement appropriate security measures
Have you implemented encryption of PII at rest and in transit?
Have you implemented pseudonymization?
Have you implemented appropriate physical security controls?
Have you implemented information security policies and procedures?
Can you access EU or UK PII data in the clear?
Do your technical and organizational measures ensure that, by default, only personal data that are necessary for each specific purpose of the processing are processed?
Streamline GDPR compliance with automation
GDPR compliance is an ongoing project that requires consistent upkeep with your system, vendors, and other factors that could break your compliance. Automation can help you stay on top of your ongoing GDPR compliance. The following items can help you streamline and organize your continuous compliance:
Explore tools for automating security and compliance.
