User and Entity Behavior Analytics (UEBA) is a cybersecurity solution that leverages advanced analytics, machine learning, and data science to monitor, detect, and respond to abnormal behaviors of users and entities (such as devices and applications) within an organization's network. It's a proactive approach that goes beyond traditional signature-based threat detection methods, focusing on behavior patterns instead.

User and Entity Behavior Analytics (UEBA) has emerged as a potent weapon in the arsenal of enterprise cybersecurity. UEBA operates on the fundamental premise that the behavior of both users and entities provides crucial insights into an organization's cybersecurity. By continuously analyzing this behavior, UEBA identifies anomalies, suspicious activities, and potential security threats.

The Key Components of UEBA

UEBA integrates several vital components to deliver its functionality:

Data Collection

UEBA platforms gather data from various sources, including logs, network traffic, and endpoints. This data may include user logins, file access, application usage, and system events.

Data Analysis

Advanced analytics and machine learning algorithms are used to process and analyze this data. UEBA systems develop baseline profiles of normal behavior for users and entities, which serve as reference points for identifying deviations.

Anomaly Detection

The system detects deviations from established baselines. These deviations can be deviations in the frequency, timing, location, and nature of activities.

Alerting and Reporting

When anomalies are detected, UEBA generates alerts and reports, which are sent to security teams for investigation and response. The system can provide context and supporting data to assist in the investigative process.

Benefits of UEBA

UEBA brings several significant benefits to the table for enterprise cybersecurity:

Early Threat Detection

UEBA excels in identifying threats early in their lifecycle, often before they can cause significant damage. By detecting subtle changes in user and entity behavior, it can uncover sophisticated, low-and-slow attacks.

Insider Threat Detection

UEBA is particularly adept at identifying insider threats—those coming from within an organization. It can detect unusual activities by employees or entities, helping organizations to prevent data breaches and IP theft.

Reduced False Positives

Traditional security solutions often generate false positives, inundating security teams with alerts. UEBA, with its behavior-driven approach, minimizes false positives, enabling security teams to focus on real threats.

Security Posture Improvement

By proactively identifying security gaps and vulnerabilities, UEBA helps organizations to continually enhance their security posture. This adaptability is invaluable in the ever-changing landscape of cybersecurity.

Application Of UEBA In Cybersecurity:

1. Insider Threat Detection: Identifying employees or entities engaged in malicious activities or data theft.
2. Account Compromise Detection: Detecting unauthorized access to user accounts or applications.
3. Data Exfiltration Prevention: Identifying and stopping data exfiltration attempts in real-time.
4. Privileged User Monitoring: Tracking the activities of privileged users to ensure they are not misusing their access.
5. Credential Misuse Detection: Detecting credential sharing, weak password usage, and other misuse.
6. Compliance and Data Protection: Ensuring compliance with data protection regulations and privacy standards.
7. Incident Response: Assisting security teams in rapidly responding to threats and incidents.

Implementation of UEBA

To effectively implement UEBA, organizations should follow these best practices:

1. Data Source Integration: Ensure integration with critical data sources such as Active Directory, SIEM logs, and endpoint security solutions.
2. Continuous Monitoring: Implement real-time monitoring and analysis to detect threats as they occur.

A spoofing attack is a type of cyberattack in which an attacker disguises their identity or falsifies information to deceive a target or gain unauthorized access to a system or network. The goal of a spoofing attack is to trick the recipient into believing that the communication or interaction is legitimate, thereby bypassing security measures and gaining unauthorized access or extracting sensitive information.

Types of spoofing attacks:

IP Address Spoofing: During the IP spoofing attack, the attacker alters the source IP address of network packets to make it seem like they are coming from a reliable source. By spoofing the IP address, attackers can evade IP-based authentication and access restrictions. With IP Spoofing, attackers can carry out denial-of-service attacks, intercept network traffic, or engage in other malicious activities.

Email Spoofing: Email spoofing involves falsifying the sender's email address to give the impression that the email originated from another origin. In this attack, attackers often pretend to be a trusted entity or organization in order to deceive recipients into disclosing sensitive information, clicking on malicious links, or opening malware-infected attachments.

DNS Spoofing: DNS spoofing occurs when cyber attackers manipulate the process of DNS resolution to redirect users to fake websites or intercept their communication. By tampering with the DNS cache or creating forged DNS responses, attackers can steer users toward malicious websites that closely resemble legitimate ones. This paves the way for phishing attacks or the dissemination of malware.

Caller ID Spoofing: Caller ID spoofing is commonly used in voice-based attacks, where attackers manipulate the caller ID information displayed on the recipient's phone to make it appear as if the call is coming from a trusted source. This technique is often employed in vishing (voice phishing) attacks, where attackers trick individuals into revealing sensitive information over the phone.

Website Spoofing: Website spoofing involves creating fraudulent websites that mimic legitimate ones. Attackers may use similar domain names, design elements, and content to deceive users into entering their login credentials, financial information, or personal data. This technique is commonly associated with phishing attacks aimed at stealing sensitive information.

Mitigating spoofing attacks:

Implementing strong authentication mechanisms: Multi-factor authentication (MFA) can help prevent unauthorized access even if credentials are compromised through spoofing attacks.

Encrypting network traffic: By using encryption protocols such as SSL/TLS, it becomes difficult for attackers to intercept and manipulate data in transit.

Deploying intrusion detection and prevention systems (IDPS): IDPS can detect and block suspicious network activities associated with spoofing attacks.

Educating users: Raising awareness among users about the risks of spoofing attacks, providing guidelines on identifying phishing emails, and promoting safe online practices can help minimize the success rate of these attacks.

Implementing anti-spoofing controls: Network-level controls, such as ingress and egress filtering, can be enforced to verify and validate the source and integrity of network packets, reducing the effectiveness of IP spoofing.

VPN is an abbreviation for Virtual Private Network. A Virtual Private Network allows to establish a safe and encrypted connection to access the public internet securely. VPN hides the user’s online identity by real-time encryption of the traffic sent or received over the internet. This makes a VPN more secure than a private WiFi hotspot.

How Does VPN Work?

In order to understand how VPN works, let us first understand the path followed by data when a user accesses the internet.

When a user sends a request to a website over internet, the data is sent or received via Internet Service Provider (ISP). Any request sent by the user is first redirected to the ISP server and then transmitted to the online service or website. Similarly, data sent by the website in response to the user request is first sent to the ISP server, which then sends it to the user. Thus ISP server has details pertaining to user’s identity, browsing history, online communications, etc. Hackers can also gain access to these details by targeting ISP servers.

VPN acts as a tunnel that bypasses ISP server. When user connects to internet via VPN, the traffic between the user and internet is sent via secure server of the VPN instead of the ISP server. VPN server acts as source server for the user. This can be understood in a stepwise manner.

1. User sends data to a website.
2. The data is received by the VPN server.
3. VPN server sends the data to internet.
4. Traffic received from internet is received by VPN.
5. VPN then serves the traffic to user.

As a result of the process, the user has no direct interaction with the internet. This keeps user’s identity and internet surfing history private. Additionally, VPN encrypts the traffic to ensure further security in case the server is hacked.

What Are The Uses Of VPN?

VPN can be used for a wide array of purposes:

1. Staying Anonymous Online: ISPs can keep an eye on your online activity including services or products you search for. This information holds high value on dark web. Using a VPN for online activity helps in keeping your credentials and online activity hidden and secured.
2. Ensure Security On Public WiFi: Public WiFi are not secured and lack data security configurations. Low security makes it easier for hackers to compromise the WiFi and eavesdrop on the traffic moving across the server. Using VPN when accessing internet over public WiFi helps in ensuring data and credentials security.
3. Data Security: Comparable to ISPs, many apps collect user data and sell it to marketing agencies. Using a VPN prevents apps from attributing data to user’s IP address, thus, ensuring data security.
4. Content Access: Content streaming platforms might publish some content for targeted locations only. For example, some shows might not stream outside US. However, users can use a VPN to mask their location and access geo-blocked content irrespective of their physical location.

Broadly internet is classified into three layers, namely, the surface web, the deep web, and the dark web. Each of these layers represents a different level of accessibility and anonymity. From a cybersecurity perspective, it is important to know what you can do safely on the web by understanding these terms and knowing what they include.

Surface Web

It is estimated that the surface web comprises less than 4% of the entire internet. The surface web, often known as the visible web, is the section of internet that is accessible via search engines like Google and Bing. This covers all web pages that are indexed by search engines and content that is accessible to everyone. An example of surface web would be the common web pages that we see and browse every day (without signup), like Wikipedia.

Deep Web

The deep web is a part of the internet that is inaccessible to normal search engines. Deep web information is not indexed by search engines such as Google as they are restricted from reaching the content using various protocols. Individuals are also restricted from browsing the information unless they have a login (or special access) and/or know the precise path (URL). It is estimated that the deep web comprises approximately 90% of the whole internet.

Some examples of the deep web are:

• Login-required social media/messaging services
• Encrypted or password-protected online banking/financial information.
• Medical records and other sensitive personal data held in systems accessible only to authorized people
• Non-public court records and legal documents
• Private forums and discussion boards that require registration and identification
• Subscription-based streaming services like Netflix
• Non-public government databases and archives.

Dark Web

The dark web is a section of the deep web that is deliberately hidden and requires specific software and protocols to access. The dark web is frequently associated with illegal activity. Browsing the dark web can be dangerous and illegal. It can expose you to malicious code/malware and viruses that can affect your computer and other devices. People should be careful and use the best cybersecurity practices to protect themselves.

It's important to know the differences between these three layers of the internet because they have different levels of risks and opportunity. The surface web is usually safe and open to everyone. The deep web and dark web, on the other hand, can be more dangerous and require more safety precautions.

How To Safely Browse Internet

• Always use a reliable antivirus solution to protect your devices from viruses, malware, and other threats. It is also important to regularly update the antivirus software for protection from the latest threats which were not identified in earlier versions.
• Use strong and complex passwords that are difficult to guess.
• Keep your software and operating system up to date to have the most recent security fixes and features.
• Be cautious of unsolicited emails and social media posts. Never give your personal information or click on a link from unknown senders.
• Using a VPN service to browse internet can protect your online activity and encrypt your interactions.
• Avoid accessing sensitive information or making financial transactions on public Wi-Fi networks.
• Practice safe browsing by visiting sites that use SSL certificates.

A Zero-Day Attack refers to a cyber security attack launched by exploiting a security vulnerability that has not yet been discovered by IT team yet. Zero-day attacks have emerged as a major cyber security challenge as there has been a significant increase in the number of zero-day attacks recently. 

Why Have Zero-Day Cyber Attacks Increased?

There are many reasons that contribute to an increase in the number of zero-day attacks.

1. Zero-day attacks can exploit security vulnerabilities at multiple levels such as in the code, configuration settings, and hardware. This widens the attack surface for the cyber criminals.
2. A global proliferation of available hacking tools is another major reason. Hacking tools are now easily available in the form of Software-as-a-Service package. This has facilitated cyber criminals to launch attacks at a rapid pace as soon as a vulnerability is detected without the need to code or fabricate attacking software.
3. Once a vulnerability is detected, the software developer has to review the code and replace the defective piece of code. This is time consuming which gives the cyber criminals an opportunity to exploit the vulnerability in the meantime.
4. After the software developer issues an update to patch the vulnerability, the users generally take time to download and install the updates. This allows hackers to exploit devices running on vulnerable software.

These technical challenges make it difficult to cope up with zero-day attacks. However, adopting some best practices in cyber security strategy can help prevent zero-day attacks.

Zero-Day Attack Prevention Best Practices

1. Well-Defined Perimeters: Identifying all the end-points connected to your organization’s network is the first step towards preventing vulnerability attacks on the devices. Now implement Endpoint protection platforms (EPP) and Endpoint detection and threat response (EDR) solutions to monitor/record user-behavior, identify malware, and block malicious scripts. To ensure efficiency of EPP and EDR solutions, it is important to lay down well-defined perimeters. 
2. Use Web Application Firewall: A Web Application Firewall (WAF) monitors and reviews all the traffic directed toward the web applications. When configurated efficiently, WAF plays a vital role in blocking malicious traffic by filtering it out and preventing the malware from exploiting any vulnerabilities. It ensures a quick response as WAF can be trained to adapt to real-time threats.
3. Deploy Multiple Security Controls: The vulnerabilities exploited by the zero-day attacks can expose devices and networks to multiple security breaches. Thus, it is important to deploy security controls which may include malware detection & prevention controls, firewalls, traffic filtering software, patch management, password & access management, and identity management solutions. 
4. Segmentize The Network: An organization uses multiple networks to perform its functions. Segmenting the networks allows the IT team to define different security controls suitable for the defined network. It also helps in containing the impact of an attack, if any, to a single network.
5. Anti-Bot Strategy: The majority of modern attacks rely on botnets. Botnets are networks of compromised machines connected to a hacker’s server by malware. If any vulnerability arises in the organization’s network, the compromised machines report it to the hacker’s server and hackers exploit the vulnerability to launch an attack. Implement an anti-bot strategy as a part of your cyber security routine. Make sure to inspect all machines or devices connected to the network to check if any of the devices have been compromised. Remove all the compromised machines from the network to mitigate the risk of an attack.

In addition to above mentioned best practices, make sure to follow cyber security hygiene including a regular update of software and hardware, password ethics, regular security inspection, etc.

Cyber security controls can be defined as the set of tools that help in prevention, detection, and mitigation of cyber crimes or threats. Cyber security controls can be broadly classified as administrative, physical, technical, and operational. Every set of controls deals with a specific threat vertical.

Different types of cyber security controls are:

1. Preventive controls
2. Detective controls
3. Deterrents
4. Corrective controls
5. Recovery controls
6. Compensating controls

In order to ensure effectiveness, every set of security controls needs to be employed efficiently. Once you have established a cyber security control strategy, it is advised to regularly test the efficiency of cyber security controls to find any misconfiguration. This helps refine the cyber security control implementation to improve the detection and prevention of cyber threats and recovery from cyber-attacks if any.

But, how can you measure the efficiency of cyber security controls?

There are numerous methods to assess security control efficiency. These methods can be classified based on their approach.

1. Indirect Assessment
2. Direct Assessment

Indirect assessment involves collecting data from sources such as perimeter servers, DNS configurations, etc., to analyze security risks likely to be faced by the organization.

Direct assessment involves testing and measuring the operations and configuration of security controls.

Let us delve deeper into methods to measure security control effectiveness:

1. Analyze Attack Surface: To understand the effectiveness of security controls, organizations first need to understand their attack surface. Attack surface refers to network backdoors that can act as entry path for cyber-attacks. The attack surface comprises exposed credentials, misconfigurations, vulnerabilities, etc.  Active Directory also constitutes a major part of the attack surface as it is one of the most desirable targets for cyber-attacks due to the important information it holds. The attack surface can be analyzed using diverse tools such as Endpoint Detection & Response tools, Extended Detection & Response tools, and Identity Threat Detection & Response tools. Gaining visibility throughout the network is the first step toward ensuring effective security controls.
2. Track Incident Response Times: One of the best ways to measure security control efficiency is to track cyber security violations or incidents. This can provide effective insight into how well the security controls are configured. Tracking the time between infestation and the first report against the problem, response time taken to fix the issue, steps taken to mitigate the issue, and if the incidents have been recurrent helps provide information about security control’s health. Additionally, check if the outcomes of the mitigation steps were favorable or not. This allows a fair analysis of effectiveness of security controls.
3. Check the Permissions: Assigning extensive access permissions to users can provide cyber criminals an opportunity to gain access to sensitive data. This makes it imperative to investigate the permissions granted to every user in the organization. Zero-Trust Architecture can help in mitigating this risk.
4. Analyze Detection Alerts: Fake alerts can deter the cyber security personnel and cause delay in detecting actual threat. Tracking False Positive Reporting Rate (FPRR) helps in improving the configuration of detection tools to ensure more accurate threat alerts. Incorporating AI and ML capabilities in the detection tools can make the detection controls more sensitive.
