Authentication Factors

Authentication Factors:
An authentication may require administrators to implement one factor of authentication for basic authentication, two factors for more authentication and more factors for higher security. In this section we will discussed the authentication factors that an organization can use for secure authentication

Something you know:
It refers to a shared secret, such as a password or even a PIN. It is the least secure authentication factor. However organizations can increase the security of password by implementing the strong password policy.

Something you have:
It refers to the something you physically hold. It includes smart cards, CAC(Common Access Cards) and hardware token.

Something you are:
It refers to the use of biometrics for authentication. It is the strongest form of authentication because they are most difficult for an attacker to falsify.

Somewhere you are:
It refers to the identification of a user based on the user’s geo location. But it is not foolproof because there are many VPNs available to change the location of individuals. It is possible to use the computer name or MAC for somewhere you are factor.

Something you do:
It refers to the actions you can take such as gestures on a touch screen. Gestures include tapping in specific places on the picture, drawing lines between items with a finger or drawing circle around an item such as someone’s head.

Dual-Factor vs Multi Factor Authentication:
Dual Factor authentication is sometimes referred to as two factor authentication. It uses two different factors of authentication, such as something you have and something you know. Dual factor authentication often uses a smart card and a PIN, a USB token and a PIN. Multi Factor authentication uses two or more factors of authentication. It combines the something you know with other one or more factors of authentication.

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...

Analyzing Spear Phishing Email

Image
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. It can also be targeted attack to focus on the specific organization of individual. The attacker often tailors an email to speak directory to targeted user. There are many types of phishing as follow. I wouldn't explain the types. You can read Here . In this article you'll learn how to analyze the sophisticated phishing email. So, Let's start the case study to explain.  Spearphising :  Spearphising is the technique in which attacker aims at one person and lures him/her into providing confidential data. Attacker compile the email according to the specific user. The email would consist some of the target's email, username, designation.  Case Study: User receive the spearphising email containing the PDF attachment with double extension. Email body contains the unprofessional statement "Kindly m...

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...
