What is Web Security?

Web security refers to a broad array of security measures designed to shield your users, devices, and network from internet-based cyber threats like malware and phishing attacks. These measures are crucial for preventing breaches and data loss. By employing techniques such as firewall inspection, intrusion prevention system (IPS) scanning, sandboxing, URL filtering, and other security controls, web security helps reduce the risk to your organization when users inadvertently access malicious files and websites.

What’s the Purpose of Web Security?

The internet has become indispensable for modern businesses, but this reliance has also led to a surge in cyberattacks in terms of their complexity, frequency, and impact. As a result, web security has become crucial for ensuring business continuity. It serves as the primary defense against threats that could result in the exposure of sensitive data, expensive ransom demands, damage to reputation, breaches of compliance regulations, and numerous other adverse outcomes.

What was once the realm of amateur hackers has now transformed into a vast underground economy, involving organized crime syndicates and state-sponsored espionage and sabotage. Today’s cyber threats are highly sophisticated, capable of deceiving even seasoned users or circumventing outdated security measures. Furthermore, with the availability of various tools, exploit kits, JavaScript modules, and even complete attack campaigns for sale, even individuals with minimal expertise can perpetrate cyberattacks.

According to Cybersecurity Ventures, global cybercrime is projected to incur annual costs of US$10.5 trillion by 2025, surpassing the profits of the world’s major illicit drug trade. Additionally, half of the world’s data is expected to reside in the cloud by then. Considering the immense potential consequences, the importance of robust web security measures cannot be overstated in today’s landscape.

What Are the Benefits of Web Security?

Effective web security offers extensive technical and human advantages for modern enterprises:

• Safeguard your business and ensure compliance by preventing the loss of sensitive data.
• Protect customers and employees by securing their private information.
• Prevent costly service disruptions by averting infections and exploits.
• Enhance user experience by enabling users to work safely and efficiently.
• Uphold customer loyalty and trust by maintaining security and avoiding negative publicity.

The advancements in cloud and mobile technologies have facilitated seamless and flexible connections for employees and customers. However, this convenience also increases the vulnerability of your organization to various attack vectors. Implementing robust web protections allows you to maximize the benefits of these technologies while minimizing concerns about security threats.

What Does Web Security Protect Against?

Web security encompasses a broad range of measures aimed at safeguarding users and endpoints from various threats, including malicious emails, encrypted threats, compromised websites and databases, malicious redirects, hijacking, and more. Let’s delve deeper into some of the most prevalent threats:

• Ransomware: These attacks encrypt data and demand ransom payments for decryption keys. Double-extortion attacks also involve data exfiltration.
• General malware: Numerous malware variants can lead to data leaks, espionage, unauthorized access, system errors, and crashes.
• Phishing: Often conducted through emails, text messages, or malicious websites, phishing tricks users into divulging login credentials or downloading spyware.
• SQL injection: Exploiting input vulnerabilities in database servers, these attacks enable attackers to execute commands for data retrieval, manipulation, or deletion.
• Denial of service (DoS): By overwhelming a network device like a server with more data than it can handle, DoS attacks slow down or disrupt services. Distributed DoS (DDoS) involves multiple hijacked devices attacking simultaneously.
• Cross-site scripting (XSS): Attackers inject malicious code into trusted websites through unprotected user input fields.
• Session hijacking: Cyber attackers can hijack user sessions by stealing HTTP cookies essential for session maintenance. Web security measures include web filtering and protection against such attacks.
• Spam: Spam emails consume network resources and storage space. Web security blocks such emails from reaching users’ inboxes.
• Advanced persistent threats: Sophisticated attacks necessitate multiple layers of security. Web security aids in early detection and prevention of malicious activities.
• Shadow IT: Unauthorized devices should not connect to the network. Effective web security blocks these devices from accessing sensitive data or resources.

How Does Web Security Work?

Web security functions operate between your environment’s endpoints and the internet, scrutinizing traffic and requests in both directions. While no single technology can monitor or inspect all traffic comprehensively, a combination of appliances, or a cloud-based service platform—increasingly effective today—offers comprehensive coverage to prevent policy breaches, malware infections, data loss, credential theft, and similar risks.

Numerous solutions are available, with varying degrees of comprehensiveness. A complete web security stack typically includes the following technologies:

• Secure web gateway (SWG): Provides threat protection and policy enforcement for users accessing the web, thwarting infections and blocking unwanted traffic.
• Firewall/IPS: Ensures network security, application control, and visibility. Cloud-based firewalls remain updated and can scale to handle encryption or demand, rendering them a practical choice.
• URL filtering: Screens and blocks inappropriate access or content, also offering defense against web-borne malware.
• Sandboxing: Isolates software in a controlled environment for scanning and execution without risking system or application infection.
• Browser isolation: Loads webpages or applications in a remote browser, transmitting only pixels to the user, thus preventing data or document downloading, copying, pasting, or printing.
• DNS controls: Establish rules governing requests and responses concerning DNS traffic, enabling detection and prevention of DNS-related abuses like tunneling.
• Antivirus: Identifies and neutralizes trojans, spyware, ransomware, and other threats. Many solutions also defend against malicious URLs, phishing attempts, and DDoS attacks.
• TLS/SSL decryption: Unveils inbound and outbound encrypted traffic for content inspection, then re-encrypts it for continued transmission to its destination.

What Technology Is Used in Web Security?

Most web security strategies comprise multiple cybersecurity tools that collaborate to fortify defenses. When choosing technology for your organization, bear in mind that not all tools or vendors are equal. To make an informed decision, prioritize essential features and thoroughly research each vendor. Upon readiness for implementation, ensure proper configuration of each tool to mitigate vulnerabilities.

Below are some prevalent web security technologies:

• Web Application Firewall (WAF): A reliable WAF thwarts sophisticated DDoS attacks and prevents malicious code injection via online form submissions. While not a standalone defense against web-based attacks, it enhances security posture and diminishes attack vectors.
• Vulnerability Scanners: All software should undergo penetration testing before deployment, but monitoring for vulnerabilities should persist post-deployment in production environments.
• Password-cracking Tools: Evaluating whether users adhere to password policies and best practices for length and complexity necessitates testing for weak passwords or network credentials.
• Fuzzing Tools: Unlike traditional scanners, fuzzing tools evaluate code in real time during development, staging, and production, offering insights into potential issues for developers to address.
• Black Box Testing Tools: Mimicking real-world threats, black box testing tools employ common exploits and malicious actions against deployed software, aiding developers in identifying and rectifying vulnerabilities.
• White Box Testing Tools: Analyzing code during development, white box testing tools offer insights into the application’s internal structure, enabling developers to avoid common coding errors and vulnerabilities.
