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
Similarly confidence interval for botnets is identified. If the observation sequence’s ALL lies within this confidence interval, then it will be considered as botnet communication. 3.4 EXPERIMENTAL RESULTS Using the experimental setup, Spyeye, Blackenergy, Zeus, Athena and Andromeda botnets are installed. Zeus, ZeuS, or Zbot is a Trojan horse malware package that runs on versions of Microsoft Windows. While it can be used to carry out many malicious and criminal tasks, it is often used to steal banking information by man-in-the-browser keystroke logging and form grabbing.
Sdbot is a worm that provides a remote attacker full access on the victim’s computer. It uses an IRC (Internet Relay Chat) protocol to establish a connection. Sdbot can spread via spam email messages; network shared drives or downloaded by another on to the computer. Backdoor function of this worm gives the attacker full access on your files. It also registers vital information from your PC such as user name and password.
There is now a classy and self-sufficient digital underground economy in which data is the illicit commodity. Stolen personal and financial data – used, for example, to gain access to existing bank accounts and credit cards, or to fraudulently establish new lines of credit – has a monetary value. This drives a range of criminal activities, including phishing, pharming, malware distribution and the hacking of corporate databases, and is supported by a fully-fledged infrastructure of malicious code writers, specialist web hosts and individuals able to lease networks of many thousands of compromised computers to carry out automated
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.
Globalisation and the rise in technology have contributed to the advancement of terrorism. Internet savvy terrorist go on to create propaganda in the online society, which could result in further recruitment of like-minded individuals. Radicals could be nurtured into terrorist ideologies. One of the recent spades of events that is an ongoing threat to society and government is cyber terrorism. Firstly, Social networking creates a platform for collaboration of individuals through the online societal context.
With the exponential increase in computer network usage and the increasing number of devices getting connected to a network, it is of great importance that they are operated securely. All computer networks suffers from one of many security flaws, the recent “Wannacry Ransomware” took cyber security industry by storm. Though there was a fix for that security loophole, organizations were lazy on applying the security patches, this behaviour of the organization can be because of organizational structure, increasing profitability or in some cases the machine is operating a critical infrastructure. Therefore, Intrusion Detection System’s (IDS) role is becoming important in tackling cyber security. Recent advances in machine learning and artificial intelligence has opened up many
Nowadays, the technology is the primary focus of all people, it may move far too quickly into the exposure of personal information. Moreover, the technological advances have been vital; there are some principles used worldwide for the information security and privacy risk mitigation. The people are initiating to store data through online; with this kind of matter, the associations who hold the information regarding the personal and other important information are the endeavor to protect these kinds of data. Though, as a result of the improvement of technology; the computer fraud, virus or identity thefts are very vivacious in terms of stealing some information of other people. Moreover, every day that people browse the internet, log on, as well as posting into the social media; it is the way of giving intentionally or unintentionally the personal information.

internet gambling), the consequences for the company can be very great. 2. Ask employees to be vigilant. Internet abuse at work can have serious repercussions not only for the individual but also for those employees who befriend internet abusers, and the organization itself. Fellow staff members need to know the basic signs and symptoms of internet abuse.
One of the biggest issues is that all services use HTTP rather than HTTPS. HTTP is used to access the firewall, Opsview monitoring, and the documentation wiki. All three of these should have their traffic encrypted, especially the firewall because if that is compromised than an attacker has much more direct access to all other systems that are behind it. It would also be recommended to use an authentication database such as Active Directory to authenticate and authorize all users for these systems. This would make it much harder to compromise accounts if the local account is not being used.
Network Security refers to any activities that take place to protect the network; more likely to protect the usability, reliability, integrity, and safety of the network and data. Targeting the threats and stopping them to enter or spread on the network is the job of effective network security. Most common threats for any computer networks are: • Viruses, worms, and Trojan horses • Spyware and adware • Hacker attacks • Identity theft • Data interception To prevent these threats, multiple layers of security need to be implemented so if one fails, other stand. Anti-virus, anti-spyware, firewall are some of the components of network security system used to block unauthorized access to the network and Virtual Private Network (VPNs), to provide
The domain is related to a browser hijacker. The rogue program works flawlessly through foundation errands. It could take you a while to recognize it. The side effects for the nearness of the hijacker are essential. Your system will be ease back to react to your solicitations.
Install antivirus and content filter software on firewalls 4. Keep all antivirus software up to date that is updating to newer and more secured versions of the anti-virus. This might cause money, but it is significantly important. 5. Keep all systems up to date, this has to do with updating required systems operating systems and other systems software for security purposes, for example the new windows 10 might have more security features than windows 7 or 8, so it’s advisable to update the operating system.
This always used to be the way that companies would manage their local admin accounts, however I recently found that this is not the most secure way of handling this process. The reasoning behind this is that the GPO has to be readable to all clients they are pushing to, therefore the hashed password that is pushed to the machine is sitting publically accessible on the DC and can easily be attacked and cracked to reveal the local admin accounts. The proper way that I have found to handle this concern is to use a tool by Microsoft called LAPS. Auditing There are a number of different auditing settings that can be put in place that cover a number of different use cases, I will be going over just a few of those use cases. Initially when diving into auditing, there are some main features that would be beneficial to have.
