This will make it much harder for the hacker to access the information easily. This is why you should see HTTPS whenever you are dealing with an online transaction. The S in HTTPS stands for secure which is a 256 byte encryption of the transmission. Additional system security requirements are secure user authentication, secure access control, reasonable monitoring to detect unauthorized access, reasonably up-to-date firewall protection, reasonably up-to-date security software (including current patches and virus definitions), and education and training of employees. By following these protocols, the banking industry has the ability and means to protect the customers’ information and
It will inform you on how hackers and system administrators used ping sweeps and port scans. While describing some of these notorious computer activities, these techniques will also be shown how system administrators can use to benefit the company. Two techniques that are used to attack a network is ping sweep and port scans. These activities can be used with malicious intent against, as well as, in effort to try to protect a network. Ping sweeps and port scans has been a notorious and yet a useful tool for hackers and system administrators.
The fact that an attacker can strike remotely makes a Web server an appealing target. Understanding threats to a Web server and being able to identify appropriate countermeasures permits us to anticipate many attacks and prevent the ever-growing numbers of attackers. The main threats to a Web server are: * Profiling * Denial of service * Unauthorized access * Arbitrary code execution * Elevation of privileges * Viruses, worms, and Trojan horses 1) Profiling: Profiling, or host enumeration, is an exploratory process used to gather information about the Web site. An attacker uses this information to attack known weak points. Vulnerabilities: • Unnecessary protocols • Open ports •Web servers providing configuration information in banners Attacks: • Port scans • Ping sweeps • NetBIOS and server message block (SMB) enumeration Countermeasures: Include blocking all unnecessary ports, blocking Internet Control Message Protocol (ICMP) traffic, and disabling unnecessary protocols such as NetBIOS and SMB.
Networked Systems Security Task 1 – THREATS AND IMPACT OF NETWORK THREATS There are many types of threats that can damage your computer either temporarily or permanently. Some threats posed may not threaten your computer right away however have the potential to do so. Some threats that present themselves can include physical threats such as the theft of equipment whether that is the monitor, computer etc. Other threats can be harder to find such as viruses, worms or any kind of malware. Understanding these threats allows the organisation to prevent, protect and correct any damage done to his/her computer to an extent.
Attackers are always looking for devices and software that are newly added to a system and not updated correctly with the security measures in place already. This is the door they look for to get in. A method to avoid such opportunities is to deploy an automated asset inventory discovery tool and use it to build a preliminary asset inventory of systems connected to an organization's public and private network. This will help make the system capable of identifying any new unauthorized devices that are connected to the network within 24 hours, and of alerting or sending e-mail notification to a list of enterprise administrative personnel. Without such a tool in place an attacker will use the unpatched device or software to gain access and manipulate the network how they please.
And to feel more secure I would purchase a firewall so that the outside would have A hard time accessing the network. I would also do a complete background check on the person that is being interviewed and or hired for the system administer
They break into our computer for several reasons but mainly to acquire personal information for financial gain, shut down hardware, steal people’s credit information, and destroy data. To protect ourselves from hackers, we should equip our computer with Firewall. This hardware “prevents unauthorized Internet users from accessing private information” (Williams & Sawyer, 2013, p. 361). Identity theft is a serious crime in which thieves steal your name and identity and use to later to make a purchase under your name. Thieves access your personal information by sending out fake e-mail, mining the trash, and stealing your
Sequence number – hijacked or interrupted TCP/IP sessions via injected packets that disguises its origination from one of the two computers in a session. Spam, and phishing attacks. Vulnerabilities of these types of attacks include: unnecessary open ports, unpatched systems, poor or outdated configurations, and exposed cabling. Countermeasures to safeguard these risks and vulnerabilities include: Access control lists, firewalls, intrusion detection systems, intrusion prevention systems, protecting network cabling, utilizing anti-virus software, private addressing, closing unnecessary ports and services, and installing security patches as necessary. • Suggest security devices or configurations that should be employed to mitigate risks existing in telecommunications.
If the anti-virus software does not contain anti-malware software, I would load the software program and check for any malware. After checking the computer for any viruses or malware, I would have the person change his password.
Unit 9 Assignment 1: List Phases of a Computer Attack In this assignment I am a hacker who needs to protect my organization from a computer attack. I will list general phases of a computer attack. We have an organization that we need to protect from outside attacks by foreign parties. I am an ethical hackers who needs to take preventative measures in order to adequately secure the network against these attacks. Many attackers follow a general set of steps in order to gain the permissions necessary to break into a system.
