- Lately, a slight change in possible targets and technology used has been witnessed. An interesting research by Kaspersky Lab’s Global Research and Analysis Team (GReAT) has highlighted how the growth of cloud technology and its use have actually given APT hackers another way to attack systems and hide more effectively between the cyber-folds.
- Another interesting trend is the creation of smaller hacking groups. Rather than large organized sets of individuals, smaller groups will be forming, effectively multiplying the number of attacks, the locations from which the attacks are carried out and number and type of targets. This fragmentation makes it harder for organizations to defend themselves and is in itself a threat.
- Also to be noted is the way targets are sought out. APT hacking groups are using a variety of techniques, including, for example, the targeting of high-level executives when staying at hotels.
- As technology advances, information security managers have more tools at their disposal to detect and bring to life stealth activities; however, APT hackers are also using new technologies to their advantage and seem to be always one step forward.
TCP (Transmission Control Protocol):- TCP (Transmission Control Protocol ) is a standard that defines how to establish and maintain a network conversation via which application programs can exchange data. TCP works with the Internet Protocol ( IP ), which defines how computers send packet s of data to each other. Together, TCP and IP are the basic rules defining the Internet. TCP is defined by the Internet Engineering Task Force ( IETF ) in the Request for Comment ( RFC ) standards document number 793. TCP is a connection-oriented protocol, which means a connection is established and maintained until the application programs at each end have finished exchanging messages. It determines how to break application data into packets that networks can deliver, sends packets to and accepts packets from the network layer, manages flow contro l , and—because it is meant to provide error-free data transmi...
