CounterSnipe Network Security
CounterSnipe is an intrusion prevention system that protects networks from malware, unauthorized access, and vulnerabilities. It works in three steps: first, it collects information about the network's assets; second, it detects unauthorized or malicious activity on the network; third, it correlates any detections with the network's assets and logs, blocks, or alerts on any violations. CounterSnipe is useful for organizations to achieve compliance, protect web applications and third-party access, enforce access policies, and augment other security measures like antivirus and firewalls.

In this Vulnerability Assessment training, you will get to learn to configure; proper training; respond to vulnerabilities that put your organization out of risk. https://www.cyberradaracademy.com/course/online-vulnerability-assessment-and-management-course-cyber-security.html
Vulnerability Assessment & Analysis (VAA) Overview
VAA (Vulnerability Assessment and Analysis) is a decision support methodology that identifies and prioritizes vulnerabilities in critical equipment and systems to deliver safe and reliable operations. It works by conducting facilitated brainstorming sessions and interviews with engineering and operations staff to produce a substantial amount of information. This information is then analyzed, categorized, and prioritized to establish a list of vulnerabilities for subsequent study using methods like FMEA, fault trees, and SIL analysis. The purpose is to validate risks identified in the initial assessment and obtain more detailed information to inform risk reduction actions. VAA can be applied to any process during any phase and provides a comprehensive final report documenting the identified vulnerabilities and prioritized action plan.

Detecting Unknown Attacks Using Big Data Analysis
Nowadays threat of previously unknown cyber-attacks are increasing because existing security
systems are not able to detect them. Previously, leaking personal information by attacking the PC or
destroying the system was very common cyber attacks . But the goal of recent hacking attacks has changed
from leaking information and destruction of services to attacking large-scale systems such as critical
infrastructures and state agencies. In the other words, existing defence technologies to counter these attacks
are based on pattern matching methods which are very limited. Because of this fact, in the event of new and
previously unknown attacks, detection rate becomes very low and false negative increases. To defend
against these unknown attacks, which cannot be detected with existing technology, a new model based on
big data analysis techniques that can extract information from a variety of sources to detect future attacks is
proposed. The expectation with this model is future Advanced Persistent Threat (APT) detection and
prevention.
NSAS: NETWORK SECURITY AWARENESS SYSTEM
The overwhelming threat may be a challenge to
general security system. Fundamentally diverse alert and threat
techniques are been researched in order to reduce deceptive
warnings. Threat Detection Systems generates huge amount of
alerts which becomes challenging to deal with them and prepare
solution. The detection System checks inbound and outbound
network activities and finds an suspicious pattern that indicate
an ongoing steps for attack. Large amount of alert may contain
false alarm therefore need of alert analysis mechanisms to offer
high level information of seriousness of threat, how dangerous
device are and which device admin has to pay more attention. To
solve this query we would make use of time and space based alert
analysis technique that provides a solution in form of attack
graph and its evaluation that provides severity of attack to
administrator.

Actionable Threat Intelligence
This document discusses threat intelligence, defining it as information about threats that can be used for action. It categorizes threat intelligence as either tactical (specific indicators like IP addresses and files) or strategic (trends and lessons from past incidents). For intelligence to be effective, it should be timely, accurate, actionable, and relevant. Traditional methods of obtaining intelligence include security vendor alerts, government reports, and automated feeds. Many security products now incorporate threat intelligence. The document stresses the importance of intelligence being actionable so security teams can respond quickly with minimal validation or manual work based on their specific context. It also cautions that intelligence integration requires a staged process and not all intelligence will be relevant to every organization.
Lecture26 cc-security1
This document discusses cloud computing security and covers the following key points in 15 sentences or less:
Cloud security involves ensuring confidentiality, integrity, and availability of data. There are four main types of security attacks: interruption, interception, modification, and fabrication. Security threats can be classified as disclosure, deception, disruption, or usurpation. Security policies define what is and is not allowed, while mechanisms enforce these policies. Security aims to prevent attacks, detect violations, and enable recovery from any successful attacks. Trust and assumptions underlie all aspects of security policies, mechanisms, operations, and issues.

This document summarizes strategies for preventing unauthorized access, discusses anti-malware software, and analyzes network traffic. It outlines strong password policies, multi-factor authentication, physical security practices, monitoring user activity, and endpoint security to prevent unauthorized access. It describes how anti-malware software uses scanning to detect malware like viruses, rootkits, and trojans. Finally, it explains that network traffic analysis provides visibility into network activity to identify anomalies and security issues.
chapter 3 ethics: computer and internet crime
This document discusses security risk assessment for a group project. It lists the group members and outlines the 8 steps to perform a security risk assessment. These include identifying assets, threats, likelihood and impacts of threats, and mitigation options. It emphasizes the importance of a complete inventory and using qualified experts. The document also covers defining security policies, prevention methods like firewalls and antivirus software, detection using IDS, and response including documentation, containment and follow up reviews.

- 9. Revisiting Security Monitoring Phase 1: Plan Phase 2: Monitor Phase 3: Action
- 11. Phase : Plan Enumerate Find Security, Network and server Devices Scope Decide which devices are in Scope for Monitoring Develop Policies Organizational Policies (which Devices will be monitored and Why) Device & Alerting Policies (Which data will be collected and how often)
- 12. Phase 2: Monitor Collect Collect alerts and log records based on the policies defined in the Plan phase. Store Collected data must be stored for future access, for both compliance and forensics. Analyze The collected data is analyzed to identify potential incidents based on alerting policies defined in phase 1.
- 13. Phase 3: Action Validate/Investigate Action/Escalate After validating a few alerts you can determine whether policies must be changed or tuned. Tuning policies must be a recurring feedback loop rather than a one-time activity
- 14. What has Changed..! Now a days monitoring only for well- defined static attacks will get you killed. Tactics change frequently and malware changes daily.
- 15. TI + SM o As you integrate threat intelligence into your security o Monitoring (SM) process, you can generate more accurate o Alerts from your security monitoring platform, lowering o The signal to noise ratio because the alerts are based on what is actually happening in the wild.
