P8.4. a. Preventive controls such as authentication so anyone trying accessing the system has to provide credentials and verify their identity, encryption so sensitive information cannot be accessed, and have a strong internal environment that educates employees on security measures. Detective controls such as log analysis could be used to show determine if someone is trying to log on to a system and is unsuccessful. Corrective controls such as having an effective CIRT that can access the laptop and block or delete important information so the theft cannot access the laptop.
Setting file permissions is a form of DAC because it is the owner’s discretion. Configuring as many security layers as the user can will ensure the server will stay secure. Not all OS are 100% secure, but they can be configured to make it very hard for a hacker to
Step 07: Avoid leaving your phone alone in public places. Hackers may infect your locked device using hardware kinds of stuff. Step 08: Do not forget to lock your phone when it is not in use. Use multiple layered securities for your device like as pattern lock, pin codes, face or voice recognition etc. Step 09: Do not plug in your phone at public charging point, it may steal your data from the device or install malware on your
Communication intelligence yields a lot of information for intelligence analysts. It is difficult to analyze such information effectively, as it requires a lot of time and analysts. This means that finding valuable information using this approach might be difficult or even impossible. The use of encryption and other secure forms of communication can restrict access to data. A change in the communications protocol, for instance, adopting another mode of communication can also lead to loss of access.
Hospitals should purchase self-encrypting hard drives. According to beckershospitalreview.com “Self-encrypting hard drives provide Source: iamwire.com stronger protection.” Encryption “uses a complex algorithm called a cipher in order to turn normalized data (plaintext) into a series of seemingly random characters (ciphertext) that is unreadable by those without a special key in which to decrypt it (makeuseof.com).” This is a very valuable asset to hospitals because if they ever got hit with a cyber attack the hackers wouldn’t be able to see what the data
Cryptography is one of widely used technique of secret writing which is the term used for data and information security and protects that information from various attacks. Cryptography is the process of converting a known text or plaintext into a human unreadable format called cipher text by encoding the original message using some encoding technique. Security is concerned with the protection of the network and data transmission over the network. Data Security is the most essential aspect of secure data transmission over the network. But to achieve complete data security is a challenging issue of data communication.
INTRODUCTION Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity . The word Steganography is of Greek origin and means “concealed writing” from the Greek words steganos meaning “covered or protected”, and graphing meaning “to write”. Steganography is the technique of hiding the message in a chosen carrier such that no one except the intended recipient is aware of its existence. Secrecy: Extraction of hidden data from the host medium should not be possible without the knowledge of the proper secret key used in the extracting procedure. Imperceptibility: After embedding the data in the medium, it should be imperceptible from the original medium.
Effective password policy is needed to prevent the passwords from being guessed or cracked. The password policy covers the passwords of all types via passwords of users, systems, databases, applications, etc.., while the password policy can be enforced where they are used frequently and by users, it is difficult to enforce for the passwords used in application to application communication. This article talks about the challenges and possible solution to eliminate embedded passwords in application. Credentials used for application to application (A2A) authentication are typically hard-coded or embedded in the configuration files of the applications. These credentials, including SSH keys are easily sought after and can be potentially exploited by cyber attackers when left
CS 507 (Assignment No 2) Part I (PHISHING) 1. Phishing. Phishing is an attempt to acquire sensitive information such as usernames, passwords and credit card details for malicious reason by masquerading as a trustworthy entity in an electronic communication. 2. How it Affect / Attack.
For consumers who usually fall victims by plainly presenting their login credentials or personal information to the identity thieves after being tricked should guard their personal identifiers. This is the most familiar intervention strategy for consumers (Giles, 2010). People should also avoid identifying themselves unnecessarily as this can partially mitigate identity theft. Maintaining computer security helps to prevent electronic identity theft through hacking, phishing or malware (Hoofnagle, 2007). People are cautioned from giving out personal information over the phone or social media platforms.
