How vulnerability scanning works

Vulnerability scanning is crucial for system security. Let's explore how these tools operate, what they uncover, and how they differ from other security tests.

Steps in vulnerability scanning

Here's how vulnerability scanning typically works:

1. Make a list of network assets
2. Set up the scanner
3. Run the scan
4. Find weaknesses
5. Score risks
6. Create a report
7. Fix issues and rescan
8. Keep scanning regularly

Common vulnerabilities found

Scanners can spot various security issues:

Scanning vs. penetration testing

Vulnerability scanning and penetration testing serve different purposes:

Scanning quickly spots issues, while pen testing shows how attackers might break in.

"Vulnerability scans expose network weaknesses, but a pen tester can show you what to do about it." - Tim Morton, Client Success Manager, Global CTI

For best results, use both methods. Regular scans catch new issues, while occasional pen tests check overall defences.

Types of vulnerability scans

Vulnerability scanning tools come in different flavours. Each type checks specific parts of your IT system. Let's break them down:

Network scans

These look for weak spots in your network. They check for:

• Open ports
• Old software
• Weak passwords
• Misconfigurations

Network scans start simple but can get complex. They're great for finding potential entry points for attackers.

Web application scans

These focus on your websites and web apps. They hunt for issues like:

• Cross-site scripting (XSS)
• SQL injection
• Broken authentication

Web app scans are crucial for keeping your online presence safe from hackers.

Database scans

These dig into your database systems. They aim to:

• Spot misconfigurations
• Find weak access controls
• Identify unpatched vulnerabilities

Database scans help keep your sensitive data locked down.

Cloud scans

Cloud scans look at your cloud-based systems. They focus on:

• Misconfigurations
• Poor access control
• Shared tenancy issues
• Supply chain vulnerabilities

IBM's 2023 Cost of a Data Breach Report found that over 80% of breaches involved cloud-stored data. That's why cloud scans are so important.

IoT device scans

These check your Internet of Things devices. They look for:

• Default passwords
• Outdated firmware
• Open ports

IoT devices often have weak security, making these scans crucial.

Using a mix of these scans helps you spot and fix a wide range of vulnerabilities before attackers can exploit them.

Key features of good scanning tools

When picking a vulnerability scanner, you need to look for tools that pack a punch. Here's what to keep an eye out for:

Setting up scanning in your organisation

Want to keep your systems safe? You need a solid vulnerability scanning plan. Here's how to do it:

Making a scanning plan

First, list all your network assets. This tells you what to scan and how often. Then, set clear goals. Maybe you want to fix all high-risk issues within 30 days?

Next, pick your scanning tools. Most companies use both free and paid options. You might use Nmap to find network devices and Qualys for deeper scans.

When to do scans

Scan frequency depends on how important each system is:

For live systems, scan during quiet hours (usually 11 PM - 5 AM) to avoid network slowdowns.

Dealing with found issues

Found a problem? Act fast. Rank issues by risk and set fix deadlines:

Keep detailed logs of all scans and fixes. It helps you track progress and spot patterns.

Scanning during development

Don't wait until your software's live to start scanning. Build security checks into your development process. It catches issues early when they're cheaper to fix.

Try running automated scans as part of your continuous integration. Developers get instant feedback on potential security flaws in their code.

Tips for good scanning practices

To get the most out of vulnerability scanning, follow these key practices:

Keep track of all systems

Make a full list of every device, app, and system in your network. This helps you scan everything that needs checking.

"A high-quality DAST solution integrated into your software development workflow... can serve as a standalone tool for finding real issues and tracking their remediation with very little hands-on interaction." - Invicti

Set up scans correctly

Configure your scans to check all needed areas. This includes both internal and external scans. Focus on high-priority assets first.

Control who can run scans

Manage who has permission to do vulnerability scans. This keeps your scanning process secure and stops unwanted scans.

Protect sensitive information

Keep private data safe during scans. Make sure you handle data securely and follow privacy rules.

Keep improving your scans

Always try to make your scanning process better. Use what you learn from each scan to improve. Stay up-to-date on new threats.

False positives can be a real pain. They waste time and money. In fact, big companies can spend up to £400,000 a year dealing with them. To avoid this:

1. Build security testing into your web development process
2. Test as early as possible
3. Use tools that fit into your development workflow

Common scanning problems

Vulnerability scanners are great, but they're not perfect. Here are some issues you might face and how to deal with them:

Incorrect results

False positives and negatives? They're a pain. Here's what to do:

• Keep your scanners updated
• Set them up right for your network
• Double-check results manually

Big networks, big headaches

Got a huge, complex network? Try this:

New threats pop up fast

Cyber threats evolve quickly. Stay ahead by:

• Scanning non-stop with AI help
• Updating your scan rules often
• Using threat intel for context

Resource juggling

Balancing scans and system performance is tough. Here's how:

• Don't run too many scans at once
• Focus on what matters most

Future of vulnerability scanning

Vulnerability scanning is evolving rapidly. Here's what's on the horizon:

AI in vulnerability detection

AI is set to transform how we identify and manage security vulnerabilities. By 2024, most scanning tools will use AI to:

• Find issues faster
• Reduce false positives
• Adapt to new threats quickly

John Burke, CTO at Nemertes Research, puts it simply: "The future of AI-driven vulnerability management is ubiquity: it will be everywhere."

Scanning in modern development

Scanning is shifting earlier in the software development lifecycle:

• Checking for issues during coding
• Identifying problems before production
• Improving developer-security collaboration

Automatic fixing of issues

We're moving towards tools that not only detect problems but solve them:

Dealing with new types of threats

As threats evolve, so do our tools. Future scanners will:

• Use AI to detect anomalies that might indicate new threats
• Perform deeper cloud system checks
• Monitor the growing IoT device landscape

By 2024, we'll see increased threat information sharing between companies, boosting collective security.

AI is powerful, but not infallible. A Seemplicity study found 71% of risk management professionals don't believe AI can fully replace human judgement in their field.

The bottom line? AI-powered tools are the future, but they'll be most effective when combined with human expertise.

Real examples

Successful scanning stories

Some big companies have nailed vulnerability scanning. Here's how:

JPMorgan Chase scans for weak spots when everyone's gone home. Smart move. They find problems without messing up work.

Google and Amazon go all-in on cloud scanning. Amazon's tool, Inspector, is always on the lookout across their massive setup.

Visma, a software company, used Qualys to scan over 10,000 devices. The results? Pretty impressive:

Their CISO said: "We now see everything. All 4,000 servers, 6,000 clients, and every vulnerability."

Learning from big security problems

When things go wrong, we learn. Here's what some orgs picked up:

NHS got hit by WannaCry in 2017. Ouch. They upped their game after that, focusing on fixing the most important vulnerabilities first.

Equifax had a MASSIVE breach in 2017. Millions of people's data, gone. After that, they:

• Watched for vulnerabilities more closely
• Got better at patching
• Tightened up security all around

Tulane University had a tough job: keeping 16,000+ people's data safe. They used Fortra VM to make it easier. Their security guy said: "Fortra VM makes the big issues stand out. We don't miss the important stuff."

The takeaway? Scan regularly, fix fast, and learn from others' mistakes.

FAQs

What are the steps in vulnerability scanning?

Vulnerability scanning is a four-step process:

1. Network scanning

The scanner pings devices or sends TCP/UDP packets to find active systems.

2. Port and service identification

It detects open ports and running services on each system.

3. System information gathering

The scanner logs into systems remotely to collect detailed info.

4. Vulnerability correlation

It compares system data against a database of known vulnerabilities.

This process helps find and fix security weak spots. For instance, a scanner might spot outdated software, misconfigured apps, or unpatched systems.

Many security frameworks, like SOC 2, HIPAA, and ISO 27001, require vulnerability scanning.

Tips for effective scanning:

• Run scans off-hours to avoid network slowdowns
• Adjust scans if systems become unstable
• Keep the vulnerability database up-to-date
