Access Control Model

Access Control Models:

Access Controls ensures that only authenticated and authorized entities can access resources.

Role Based Access Controls:
It uses roles to manage rights and permissions for users.This is useful for users within a specific department who perform the same job functions. An administrator creates the roles and then assigns the specific rights and permissions to the roles instead of users.

Rule Based Access Controls:
Rule Based Access Controls uses rules. Rules can be static and dynamic. Static rules are implemented on routers or on firewalls. Examples of dynamic rules are IPS then modify rules to block the traffic from an attacker.

Discretionary Access Controls:
Every object has an owner, and the owner establishes access for the objects. 

Mandatory Access Controls:
It uses labels sometimes referred to as security labels to determine access. Administrators assign labels to users and files/folders. When the label matches then the system grants access to that files/folders. When the label doesn't match, the access model blocks the access.

Attribute Based Access Controls:
It evaluates attributes and grants access based on the value of these attributes. Attributes can be any attributes and grant access when the system detects a match.

Cyber Threat Intel

What is Cyber Threat Intel? Threat intel is the information about the threats. Cyber threat intel is used to better understand, predict and adopt to the behavior of malicious actors. It plays an important role in preventing the zero-day attacks. " Threat information that has been aggregated, transformed, analyzed, interpreted, or enriched to provide the necessary context for decision-making processes " (NIST). Threat Intel life Cycle: Intelligence lifecycle is the process of developing raw information into finished intelligence for policymaker to use in decision making and action. CTI Life Cycle Planning and Direction Planning and direction helps in setting up the goals for the threat intel program. Priorities and requirements are defined in this phase. Collection: Collection means gathering of data to produce the finished intelligence. Data includes logs(Firewall, IPS/IDS, Endpoints), threat feeds and OSINT(reports, social media, public forums). Collection Types of Collectio...

Phishing is the technique of fraudulent attempt by the attacker to obtain sensitive and confidential information i.e. Credentials, PII information, credit card, bank details.

Advance Attacks on Network

  Advance Attacks and Protection: In this section we will discuss some common types of attacks that can be launched against the systems and networks. Spoofing: Spoofing occurs when one person or entity impersonates or masquerades as someone or something else. There are two common types of spoofing attack one is IP spoofing and the other one is MAC spoofing. We can prevent IP spoofing by blocking the packet if it contains the private IP address on public interface. SYN Flood Attack: The SYN Flood attack is a common attack used against servers on the internet. They are very easy for attackers to launch and difficult to stop, and can cause significant problems. It can disrupt the TCP handshake process and can prevent legitimate clients from connecting. In a SYN flood attack, the attacker never completes the handshake by sending the ACK packet. So it consumes the server resources. We can prevent it by setting the threshold for SYN packet. MITM: Man in the Middle attack is a form of act...
