Answer:
Brute Force attack.
Explanation:
A network is a platform where end user devices like computers are connected to communicate and share resources. There are public networks and private networks.
A public network has its end devices and servers configured with a public IP address, which is routable on the internet, while private networks uses private IP addresses which can be used on the internet.
Private networks can be made accessable to public users by configuring an authentication and authorization policy, which could be one or a multi factor authentication. These requires a password and other factors to access the services of a private network.
An attacker can easily access a one factor or a password accessible user account, if the password is weak by using the process called a brute Force attack.
The brute Force attack exploits the vulnerability of weak passwords by entering possible valid combination from a defined set of possibilities.
Answer:
Option (A) is the right answer.
Explanation:
According to the scenario, the user system is giving the error of invalid certificate while other users on the same network do not report any error, which means that there is some problem in a particular system.
Date and time can also be one of the main cause of this error because wrong date and time creates problem in surfing many websites by giving certificate error.
Hence the most appropriate answer is option (A).
While other option are wrong because of the following reasons:
- UEFI boot mode is mainly used in booting the operating system and has no connection with network.
- Logon time is also wrong because if the problem is with the login server, it can not give certificate error.
- User access control is also not correct because it is used to control the access of the user.
/etc/services on my CentOS machine goes up to 49000. Reserved ports are less than 1024.
Well known and reserved ports are two different things. Well known ports only need a registration with IANA. Reserved ports, on *nixes, requires root for a deamon to bind to the port.
