Detect Website Vulnerabilities & Security Flaws before Hackers Do

Hi there!

As an online business owner, protecting your website from cybercriminals is absolutely critical. Your website is the digital front door to your business – but it can also be the gateway for hackers to steal data, spread malware and damage your reputation.

In this comprehensive guide, I‘ll explain step-by-step how you can proactively detect website vulnerabilities using advanced cloud-based tools before hackers exploit them. By finding and fixing security flaws in your web applications, you can dramatically strengthen defenses and avoid devastating data breaches.

Why Continuous Website Security Scanning is Essential

Your customers trust you with their data and expect it will be protected. A single vulnerability can destroy that trust in an instant. Major breaches from unpatched flaws have impacted huge brands like Home Depot, Yahoo, Uber, and Marriott with millions in damages. Small businesses are especially attractive targets for hackers seeking to extort money.

The threat landscape is also evolving rapidly – over 421 million new malware variants were discovered in 2020 alone according to AV-Test. Automated attacks make it possible to probe millions of sites quickly, looking for low hanging fruit. Once inside, hackers will move laterally through your network until they achieve their objectives.

The key is identifying vulnerabilities before the bad guys do. By proactively scanning your website and fixing any flaws found, you can ensure there are no easy pathways in. This prevents you from ending up in the headlines for the wrong reasons!

Top Website Vulnerabilities Targeted by Hackers

Hackers pray on a multitude of vulnerabilities to intrude into websites, including:

1. SQL Injection (SQLi)

SQL injection enables hackers to access and manipulate backend databases using malicious inputs on forms, searches and other entry points. According to the 2021 HackerOne Hacktivity report, SQLi was the #1 most common weakness exploited. A single SQLi vulnerability can lead to massive data theft.

2. Cross-Site Scripting (XSS)

XSS flaws allow attackers to inject malicious JavaScript code into pages viewed by other users. XSS was the second most commonly attacked vulnerability class per HackerOne. Successful XSS attacks can lead to account hijacking, data exfiltration, and malware distribution.

3. Broken Authentication

Authentication weaknesses enable unauthorized access to accounts through techniques like credential stuffing, weak passwords, and flawed remember me functions. These are highly coveted by hackers seeking to impersonate legitimate users.

4. Sensitive Data Exposure

Unencrypted sensitive data including customers‘ personal and financial information is a goldmine for cybercriminals if exposed. Security misconfigs can unintentionally leave databases and backups openly accessible.

5. Security Misconfiguration

Misconfigured servers, software, and cloud services frequently contain default accounts/passwords, unnecessary services running, and other avoidable risks. These issues are routinely uncovered in penetration tests.

6. Cross-Site Request Forgery (CSRF)

CSRF tricks logged-in users into unknowingly executing malicious actions like money transfers or email list subscribes. CSRF often slips under the radar of traditional scanners.

7. Local/Remote File Include (LFI/RFI)

LFI/RFI enables arbitrary file reading (LFI) or malicious code execution (RFI) on the server by exploiting vulnerable inclusion functions. These flaws allow hackers to breach websites as a starting point to further infiltrate networks.

This covers many of the most common vulnerabilities, but new risks emerge constantly. Regularly scanning your website is the only way to stay on top of risks.

Shocking Website Vulnerability Statistics

According to web security leader Invicti Security‘s 2022 Web Applications Security Report, 98% of web apps contain exploitable vulnerabilities, with each site having an average of 11 serious risks, including:

• 89% of sites are vulnerable to XSS. This was the #1 vulnerability found.
• 66% of sites contain sensitive information exposure risks like unprotected databases.
• 62% of sites are vulnerable to SQL injection which could lead to data loss.
• 55% of sites have broken authentication vulnerabilities enabling account takeovers.

These statistics reveal how prevalent security flaws are on production websites – and why continuous scanning is essential to finding and closing gaps before it‘s too late.

Capabilities of Cloud Website Vulnerability Scanners

Traditionally, web vulnerability scanning required purchasing, deploying and maintaining an internal appliance. However, purpose-built cloud website vulnerability scanners now offer a much easier and more powerful option:

Key capabilities include:

• Fully automated scanning – Crawls entire sites and automatically detects vulnerabilities without any manual testing needed. Scans for SQLi, XSS, LFI, RFI, CSRF and 100+ other flaws out of the box.

• Authenticated scanning – For deeper insight, the scanner can log into your web apps as a user would including handling multi-factor authentication. This surfaces flaws only visible to authenticated sessions.

• Malware scanning – Identifies infections including injected spam links, phishing scripts, malware uploads and other backdoors. Critical for ecommerce and user-generated content sites.

• Audit reporting – Detailed technical reports summarize all vulnerabilities found and provide mitigation guidance mapped to CWE, OWASP Top 10, PCI DSS and other standards.

• Scan scheduling – Flexibly schedules scans on a recurring daily, weekly or monthly basis to fit your development cycles. Alerts notify you once scans complete.

• DevSecOps Integrations – APIs support integrating scans into CI/CD pipelines enabling "security as code". Find flaws before new code ever reaches production.

• Continuous scanning – Monitors production sites 24/7, alerting immediately whenever new vulnerabilities emerge to accelerate response.

• Virtual web app firewall – Analyzes findings to auto-generate mod_security firewall rules specifically tuned to block newly detected vulnerabilities.

These powerful capabilities allow cloud scanning solutions to provide comprehensive protection for even complex modern web applications – all without needing to deploy an internal scanner appliance and server.

Why Choose a Cloud Web Vulnerability Scanner?

Here are the top benefits of using an external cloud web vulnerability scanning service:

• No hardware/software to install – Cloud scanners are accessed fully remotely via web dashboards without installing an on-premise scanner or any agents. You can start scanning immediately without deployment hassles.

• Scanner maintenance eliminated – No need to patch, upgrade or maintain an internal scanner appliance yourself as the provider handles this behind the scenes.

• Always up-to-date – Cloud scanner‘s vulnerability definitions are continually updated meaning more accurate results versus intermittent internal scanner signature updates.

• Global scanning infrastructure – Distributed scanners across regions enables safely scanning public sites without originating scans from your own IP ranges.

• Scales on demand – Cloud scanner capacity scales seamlessly allowing auditing large complex sites without bandwidth/hardware limitations.

• Accessibility from anywhere – Scan results can be securely accessed from anywhere rather than being restricted to internal networks. Enables remote teams to collaborate.

• DevOps integration – Integrating scans into CI/CD pipelines for automated testing during commit and build events enables shifting security left.

• Predictable TCO – Subscription pricing allows projecting costs versus large intermittent capital expenditures for on-premise scanners.

For organizations without large security teams, cloud scanners provide an efficient means to regularly audit web apps for risks cost-effectively.

Step-by-Step Guide to Scanning Your Website for Vulnerabilities

Now that I‘ve explained the importance of web vulnerability scanning and key scanner capabilities, let‘s walk through the 6 steps to scan your site:

Step 1: Create a Cloud Scanner Account

• Signup for a free trial of a scanner like Invicti Security. Most providers offer free plans for open source projects as well.

• Enter basic contact information during signup. Make sure to provide a real email address to receive notifications.

Step 2: Add Your Website for Scanning

• After logging into your scanner account, you‘ll see a dashboard to configure your first scan.

• Enter your website URL and select "Scope" – choose "Crawl entire domain" for the most comprehensive scan.

• If you want authenticated scanning, also enter valid credentials enabling deeper discovery of flaws.

Step 3: Verify Website Ownership

• To prevent abuse, scanners require verifying control of the site being scanned through a unique token placed in DNS records, an HTML comment, the .well-known folder or by uploading an authorization file.

• Just follow the specific instructions shown in your scanner dashboard to complete this ownership verification. It only takes a minute.

Step 4: Configure Advanced Scan Settings

• Prior to launching your scan, you can customize advanced settings:

  • URL crawl scope – how many pages deep to map out your site‘s structure

  • Audit scope – scan just frontend or also include APIs and web services

  • Detection sensitivity – balance false positives vs false negatives

• Stick with the defaults initially if unsure – you can refine later after reviewing results.

Step 5: Start the Vulnerability Scan

• Once your site is configured and ownership verified, kick off your on-demand scan with a single click.

• Larger, complex sites may take a few hours to fully scan. You‘ll receive an email when the scan completes.

• For continuous scanning, enable scheduled scans on a recurring daily, weekly or monthly basis. This will automatically retest your site for new threats.

Step 6: Review & Address Detected Vulnerabilities

• When complete, the scanner dashboard summarizes discovered vulnerabilities by severity with trend graphs.

• Click into specific findings to see technical details like HTTP requests, stack traces and remediation guidance to help fix quicker.

• Export full scan reports as PDF, CSV or XML to share findings with your developers. Schedule a rescan after fixing to confirm issues are addressed.

• Implementing scanning in your SDLC ensures new vulnerabilities are caught before ever reaching production.

Following this process will get you started revealing holes in your web apps before they become cyber attack entry points. Stay vigilant by scanning frequently to check for emerging risks.
