Computer Security

Senior leadership, in collaboration with the information security team and HR, should decide where the information security function should be located in the organizational structure. Factors such as reporting lines, strategic alignment, and resource allocation should be considered when making this decision.

It is difficult to pinpoint a single country that produces the most or deadliest viruses as they can originate from various countries worldwide. Similarly, attributing hacking activities to a single country is complex as hackers can operate from anywhere in the world. It's important to approach these topics with caution and avoid generalizations. For credible information, consider consulting reputable sources such as security reports or cybercrime databases.

The Federal Information Security Modernization Act (FISMA) requires all users of federal computers to be trained in information systems security concerns. This act outlines the requirements for federal agencies to develop, document, and implement security programs to protect their information and systems.

Non-repudiation is the inability to deny sending a message, and is usually accomplished via digital signatures or a trusted third party (TTP).

If the signature is known to belong to the sender, then we can assume that any message sent using that signature was sent with the knowledge of the sender. Therefore, the sender can not later say, "I never sent a resignation letter" when we have a digitally signed message saying otherwise. This method is common with asymmetric (public key) cryptography.

When using a TTP, the sender will send a message (signed or not) to a third party which the sender and receiver have previously agreed upon, the TTP then forwards the message to the final recipient(s). This method of transmission is generally used with symmetric (private key) cryptography. Because the TTP has received the message, they essentially act as witnesses, so the sender can not deny having sent a message.

The caveat with non-repudiation is that we assume the keys have not been compromised - but that's another discussion. The mechanics of how these forms of cryptography work can be found elsewhere on this site, or at sites dedicated to IA, cybersecurity, and cryptography.

Physical threats are those which impact your body, mind, or solid goods. These would be anything from an unlocked door, to a stalker.

Threats to data relate more specifically to informaton--things you cannot directly hold in your hand. These could be anything from a untrustworthy employee in a Social Securiy office, who may steal information about you, to an unprotected computer or server with information about you, which could be hacked.

There are different components of an information system, there are routers/firewalls, servers, PCs. The best way to manage them it to ensure they communicate with each other, and keep them up to date on patches, IOS, OS, virus defs, etc.

Manual systems in elections are prone to human error, such as miscounting or misplacing ballots, which can lead to inaccuracies in the results. They can also be time-consuming and resource-intensive due to the manual processes involved. Additionally, manual systems may be more susceptible to fraud or manipulation compared to modern electronic voting systems.

The frequency of password cracking attempts can vary depending on the individual's online activity and security measures in place. Users with weak passwords or those who reuse passwords are more at risk of being targeted for password cracking. It is recommended to use strong, unique passwords and enable two-factor authentication to help protect accounts from unauthorized access.

okay, i think this is the easiest way to explain this is by explaining the different kinds of hacking.

there are three kinds of hackers, there are white hat hackers, gray hat hackers, and black hat hackers.

white hats to legal things for good purpose.

gray hats do illegal things for good purpose

black hats do illegal things for bad purpose (ex: to harm someone)

for a true definition of a hacker check out the hackers manifesto.

a criminal is someone who does anything illegal

Before the Internet, criminals had to dig through people's trash or intercept their mail to steal their personal information. Now that all of this information is available online, criminals also use the Internet to steal people's identities, hack into their accounts, trick them into revealing the information, or infect their devices with malware.

That depends on what they do while hacking and their age. Sending an 11 year old script kiddie to jail probably won't be as effective as bringing his parents into it, having his computer privileges revoked and making him do community service. On the other hand someone who writes malware and embeds it as a Trojan in software so that they can hack computers to join them to a botnet DO belong in jail - preferably with a lifer named Bubba who wants to "have some fun with them". - ok I admit, I hate spammers and people who release scareware, spyware, etc. but the harm these people do is very expensive in terms of lost time and productivity not to mention the theft of services and aggrivation they are guilty of.

A malicious insider is an employee or authorized person who uses his data access for harmful, unethical, or illegal activities. Because of the wider access available internally, insiders are often harder to detect and apprehend than external attackers or hackers.

Life experiences such as financial struggles, personal grievances, feeling undervalued or unappreciated, or exposure to criminal influences could potentially turn a trusted user into a malicious insider. These experiences may cause someone to rationalize unethical behavior or seek retribution through unauthorized actions within their organization.

An authorization password is a security code or passphrase that verifies a user's identity and grants access to certain systems, applications, or accounts. It helps protect sensitive information and prevents unauthorized users from gaining entry.

Uncas also revealed the bracelet that Cora had given to Alice as a token of their sisterly bond.

Many hosts participate in a coordinated attack. They send an overwhelming number of transactions to the target site, effectively blocking real traffic. In some cases, the huge volume will CRASH the site's servers.

To set up SSH with DSA/RSA public key authentication, you need to generate a key pair on the client machine using a command like ssh-keygen. Then, copy the public key to the server's ~/.ssh/authorized_keys file. Finally, make sure the permissions on the ~/.ssh/ directory and the authorized_keys file are secure (e.g., chmod 700 ~/.ssh and chmod 600 ~/.ssh/authorized_keys).

The limits of an electronic information system, such as storage capacity or processing speed, can affect the amount and type of information that can be accessed on the system. If the system has limited storage, for example, it may only be able to store a limited amount of information, resulting in some data being inaccessible. Additionally, the security level of users can impact the information accessible on the system, as users with lower security permissions may be restricted from accessing certain sensitive or confidential information.

People can protect themselves from computer crimes by keeping their software and operating systems up to date with the latest security patches, using strong and unique passwords for all of their online accounts, being cautious of suspicious emails and links, and using reputable antivirus and anti-malware software. Additionally, it is important to regularly back up important files and data, and to avoid using public Wi-Fi networks for sensitive activities.

you go to your profile page and look up your account info and scrool down were your password is at .there should be a link that says change password .click the link and delate your password and put in a new password

Almost certainly not. It uses a protocol simple enough for it to not have any vulnerabilities, and even if there would be a security hole, you're safe in singleplayer.

Long answer made short: * learn what asm is (short for assembly code) * learn how to reverse engineer (get the assembly code of a program, a debugger is most commonly used) * learn a programming language basics (mainly how to read and write to memory) You can then reverse your program, find what you need to change, and create an external program to edit the part you wish to change. (otherwise known as memory hacking, or mem hacks) to crack, its the same, reverse, locate, however, you then have to permantly change part of the program. this is often done to bypass serial codes. a JE is changed to JNZ, or simply JMP.

decryption is the process of extracting the original information from the encrypted data.
