What is Security Protection?

An article about security, types of security protection, importance of network security and solutions.

In today's digital world, security protection has become a crucial aspect of our daily lives, whether it's in the digital realm or our physical environment. This means protecting sensitive information from being accessed by unauthorized individuals. This could include personal details, financial information, or confidential business data. Breaches of privacy can lead to identity theft, financial fraud, and a loss of trust in digital systems. The importance of effective security measures cannot be overstated, as they safeguard our personal information, assets, and even our personal safety.

What are the Common Network Security?

Cyberthreats encompass a wide array of attack vectors. The most dangerous advanced threats today include ransomware, phishing campaigns, zero-day attacks, vulnerability exploitation, DDoS attacks, injection, and malware. From transmission layer security to email security, VPN security, web application security, WAF security, zero trust security, SSL security, and overall network security solutions, each aspect plays a crucial role in safeguarding our digital environment.

1. Transmission Layer Security (TLS)

What is a TLS handshake?

TLS or Transport Layer Security is an important aspect of your website. It protects user data from security threats such as malware and Denial of Service (DoS) attacks. Having TLS ensures that only authorized users can access the data through encryption. For example, using TLS encryption for an online store will protect customers' transactions by converting their sensitive data into passwords. This way, third parties will not be able to read the data.

Here are some key reasons highlighting the importance of TLS: Data Confidentiality, Data Integrity, Authentication, Trust and User Confidence, Compliance Requirements, Mitigating Network Attacks, Secure Remote Access.

2. Email Security

Email security involves various techniques for keeping sensitive information in email communication and accounts secure against unauthorized access, loss, or compromise. This includes spam filters, phishing detection, and encryption.

Why is Email Security important?

Here are some key reasons highlighting the importance of Email security: Privacy Protection, Data Leakage Prevention, Prevention of Malware Propagation, Defense against Phishing Attacks, Compliance Requirements, Reputation and Trust, Safeguarding Business Interests.

  • Protect confidentiality: Emails often contain sensitive information, such as personal or financial data or business secrets, so this information must be protected from unauthorized access. Without proper email security, this information can easily be intercepted and leaked.
  • Maintain email integrity: Email messages can be tampered with during transmission, making it possible for someone to modify the content of the message without the sender or recipient's knowledge. Ensuring email integrity ensures that information is not tampered with during transmission.
  • Ensure availability: Email security is also important to ensure the availability and availability of your email system. Email systems can be targeted by attackers, and without appropriate security measures, systems can be disrupted, resulting in downtime, lost productivity, and potential data loss.
  • Maintain compliance standards: Many industries and organizations are subject to various regulations and compliance standards that require them to protect sensitive information. Implementing email security measures can help meet these compliance requirements and avoid costly fines and penalties.

3. VPN Security

A Virtual Private Network (VPN) extends a private network across a public network, enabling users to send and receive data securely across shared or public networks as if their devices were directly connected to the private network.

4. Web Application Security

This refers to the protection of websites and online services against different security threats that exploit vulnerabilities in an application's code. Common targets for web application attacks include content management systems (CMS), databases, and software interfaces.

What are common web application security risks?

  • Cross-Site Scripting (XSS): Attackers inject malicious scripts into web pages, allowing them to execute in users' browsers and steal sensitive information or perform other malicious actions.
  • Cross-Site Request Forgery (CSRF): Attackers exploit users' authenticated sessions to send unauthorized requests without their knowledge, leading to actions such as changing passwords or initiating unauthorized transactions.
  • SQL Injection: Attackers inject malicious SQL code into user input, bypassing application validation and filtering mechanisms to gain unauthorized access to or manipulate sensitive data in the database.
  • Unauthenticated and Unauthorized Access: Applications fail to properly authenticate and authorize users, allowing unauthorized individuals to access sensitive data or perform privileged operations.
  • File Upload Vulnerabilities: Applications do not properly validate and filter user-uploaded files, enabling attackers to upload malicious files and execute arbitrary code or gain system-level access.
  • Insecure Session Management: Applications fail to properly manage user sessions, such as improper use of session identifiers or failure to destroy sessions in a timely manner, leading to session hijacking or session fixation attacks.
  • Sensitive Data Leakage: Applications fail to adequately protect stored sensitive data, such as user passwords or credit card information, resulting in data breaches that compromise user privacy and security.
  • Insecure Third-Party Components and Libraries: Applications utilize third-party components and libraries with known security vulnerabilities, allowing attackers to exploit these vulnerabilities to compromise the application or access user data.
  • Improper Error Handling and Information Disclosure: Applications leak sensitive information during error handling, such as database error messages or stack traces, providing valuable information to attackers.
  • Insufficient Access Controls: Applications fail to implement proper access control mechanisms, allowing unauthorized users to access sensitive functionality or data.

5. WAF Security

A Web Application Firewall (WAF) is a specific form of application firewall that filters, monitors, and blocks HTTP traffic to and from a web application. It provides protection from various attacks such as cross-site scripting (XSS) and SQL injection.

6. Zero Trust Security

This security model assumes no trust for any entity inside or outside the network. It requires strict identity verification for every person and device trying to access resources on a private network, regardless of whether they are sitting within or outside of the network perimeter.

7. SSL Security

Secure Sockets Layer (SSL) is a standard security technology for establishing an encrypted link between a server and a client. It ensures that all data passed between the web server and browsers remain private and integral.

Tencent EdgeOne protects your websites, apps, and APIs by intelligent identification to block various attacks, mitigates DDoS threats, and employs AI and bot policy engines to analyze web, bot, and CC attacks.

1. DDoS Protection(DDoS protection at the network layer)

A Distributed Denial of Service (DDoS) attack refers to an attacker remotely controlling a large number of zombie hosts through the network to send a large number of attack requests to one or more targets, blocking the target server's network bandwidth or exhausting the target server's system resources, making it unable to respond to normal service requests.

DDoS protection can effectively ensure availability and continuity, monitoring network traffic in real-time, and immediately cleaning up traffic-based DDoS attacks when detected.

2. Web Protection

Web Protection can control and mitigate various risks, with typical scenarios including:

  • Vulnerability attack protection: For sites involving customer data or sensitive business data, you can enable managed rules to intercept injection attacks, cross-site scripting attacks, remote code execution attacks, and malicious attack requests from third-party component vulnerabilities.
  • Access control: Distinguish between valid and unauthorized requests to prevent sensitive business exposure to unauthorized visitors. This includes external site link control, partner access control, and attack client filtering.
  • Mitigating resource occupation: Limit the access frequency of each visitor to avoid excessive resource occupation, which may cause service availability decline.
  • Mitigating service abuse: Limit session or business dimension abuse, including batch registration, batch login, excessive use of API, and other malicious usage scenarios. Strengthen the usage quota of a single session (such as users, instances, etc.) to ensure that users use service resources within a reasonable limit.

3. Bot Management

Bot management is a service that maintains the quality of your website traffic. Among your website visitors, there may be a portion of visits that are not initiated by real users, but by automated programs, which we usually call bots. Although some bots (e.g., search engine crawlers) are beneficial to the website, they may also cause the following issues:

  • Abnormal website traffic or performance degradation: A large amount of bot traffic may consume a lot of server resources, affecting the access experience of real users. In this case, bot management helps to identify and control these bots, optimizing website performance and improving user experience.
  • Abnormal data statistics: This may be caused by bots simulating user behavior. Bot management can more accurately distinguish between real user and bot behavior, allowing you to obtain more realistic data.
  • Website content or user information leakage or abuse: Bots may try to crawl and copy website content or obtain user personal information. Bot management can effectively block unauthorized access, protecting the security of website content and user information.
