Do you know what the main types of access attacks are?

The term access is broad and refers to the manipulation of data, access to a system or the escalation of unauthorized privileges. La recuperación de datos no autorizados es simplemente leer, escribir o mover archivos que no están destinados a ser accesible para el intruso. Los ataques de acceso requieren una capacidad de un intruso de obtener acceso a una máquina a la que no se le permite acceder (como cuando el intruso no tiene una cuenta o contraseña). Un ejemplo puede ser ganar las credenciales de un titular de cuenta para conectar un hardware extranjero directamente a la infraestructura de red. Entrar o acceder a sistemas a los que no tiene acceso generalmente implica ejecutar un hack, un script o una herramienta que explota una vulnerabilidad conocida del sistema o la aplicación que está siendo atacada.

Access attacks are generally distinguished between:

A. Logical access attacks such as exploitation through brute force attacks or network password testing by rainbow tables or dictionary attacks that tend to create a ton of network traffic and can be easily identified by even an experienced lower level network monitor. It is for this reason that most logical access attacks usually come after sufficient acknowledgments or credentials have been obtained. There is also a tendency to rely on the passive side of attack such as man-in-the-middle to try to gather more information before becoming overly suspicious.

B. Physical access attacks such as hardware access or user access. Here we find for example social engineering attacks, these are very damaging and difficult to defend against because their users are usually the weakest link in cybersecurity. The simplest type of social engineering attack consists of sending phishing emails designed as a hook, or getting a keystroke on an insider’s computer to gain credentials that can escalate the attacker’s privileges.

What are the most common access attacks?

– Password attack

Here threat actors attempt to discover critical system passwords using various methods such as phishing attacks, dictionary attacks, brute force attacks, sniffing or social engineering techniques. Brute-force password attacks involve repeated attempts using tools such as Ophcrack, L0phtCrack, THC Hydra, Rainbowcrack and Medusa.

– Pass-the-Hash or PtH attack

In this case, the threat actor already has access to the user’s machine and uses the malware to gain access to stored password hashes. It then uses the hashes to authenticate to other remote servers or devices without using brute force.

– Trust Exploitation

Cybercriminals here use a trusted host to gain access to network resources. For example, an external host accessing an internal network over VPN is trusted. If that host is attacked, the attacker can use the trusted host to gain access to the internal network.

– Port redirection

Refers to when a threat actor uses a compromised system as a base for attacks against other targets.

– Man-in-the-middle attack

Positions itself between two legitimate entities in order to read, modify or redirect data passing between the two parties.

– IP, MAC, DHCP Spoofing

Spoofing attacks are attacks in which one device attempts to impersonate another by spoofing address data. There are multiple types of attacks. For example, MAC address spoofing occurs when a computer accepts data packets based on the MAC address of another computer that is the actual destination of the data.

Most importantly, what would be the solution?

These attacks are radically reduced when network security is strengthened. Most companies are limited to the capabilities of their equipment, so if the company’s router is vulnerable to attack, then it is necessary to set up rules in your network IDS / IPS for its protection. Additional measures include monitoring the probe for any newly recognized reconnaissance attacks. redborder NIPS has advanced measures against suspicious traffic. It not only monitors the traffic, but also acts on the traffic it monitors, generally blocking or dropping the traffic. Threat or malicious traffic detection is handled by signature-based detection, allowing it to easily and quickly recognize known bad traffic from sources such as botnets, worms or other common attack vectors on the Internet.
