What is the name of the method used to illicitly target a senior person in an organisation so as to try to coerce them Into taking an unwanted action such as a misdirected high-value payment?
Which of the following is an asymmetric encryption algorithm?
RSA (Rivest-Shamir-Adleman) is a widely accepted asymmetric encryption algorithm. Unlike symmetric algorithms, which use the same key for both encryption and decryption, asymmetric algorithms use a pair of keys -- a public key for encryption and a private key for decryption. This method allows for secure key exchange over an insecure channel without the need to share the private key. RSA operates on the principle that it is easy to multiply large prime numbers together to create a product, but it is hard to reverse the process, i.e., to factorize the product back into the original primes. This one-way function underpins the security of RSA.
A penetration tester undertaking a port scan of a client's network, discovers a host which responds to requests on TCP ports 22, 80, 443, 3306 and 8080.
What type of device has MOST LIKELY been discovered?
The ports discovered during the port scan are indicative of the services that are likely running on the device. Here's a breakdown of what each port typically signifies:
TCP port 22: This is commonly used for Secure Shell (SSH) which is used for secure logins, file transfers (scp, sftp) and port forwarding.
TCP port 80: This port is used for Hypertext Transfer Protocol (HTTP), which is the foundation of data communication for the World Wide Web; essentially, it's the standard port for web traffic.
TCP port 443: This is used for HTTP Secure (HTTPS). It's the protocol for secure communication over a computer network within a web browser, providing a secure version of HTTP.
TCP port 3306: This is the default port for the MySQL database, which is often used in conjunction with web applications.
TCP port 8080: This is an alternative to port 80 and is used for web traffic, particularly for proxy and caching.
Given this information, the most likely type of device is aWeb server, as it uses these ports for web traffic, secure communication, and potentially for a database that supports web applications.
One traditional use of a SIEM appliance is to monitor for exceptions received via syslog.
What system from the following does NOT natively support syslog events?
Syslog is a standard for message logging and allows devices to send event notification messages across IP networks to event message collectors - also known as Syslog servers or SIEM (Security Information and Event Management) systems. Native support for syslog is commonly found in various network devices and Unix/Linux-based systems.
Enterprise Wireless Access Points,Linux Web Server Appliances, andEnterprise Stateful Firewallstypically have built-in capabilities to generate and send syslog messages to a SIEM system for monitoring and analysis.
