1. The most common types of system access controls
Access control determines allowed activities of legitimate users, mediating every attempt by a user to access a resource in the system and prevent unauthorized users to access the system. It requires unique user identification, emergency access procedure, automatic log-off, and encryption and decryption of data. Some common types of access control include: User-based, Role-based and Context-based access control with the strongest security on Context-based access control. “LaTour, Kathleen M. (2010) AHIMA. Health Information Management – Concepts, Principles and Practice– 3rd edition. Chapter 9 Pages 255”.
The steps of access control process are:
a) Identification to unique user ID. It can be a combination of first and last name.
b) Authentication which contains known by user (like password, PIN, Phrase and pass code), accessories own by user (like Keypads, smart cards and tokens) and something personally related to the user’s body (Biometric systems including voice recognition, fingerprinting and retinal scanners).
c) Accounting which limits access of the users to the minimum necessity. Accountability for user’s action needs to control by audit trails.
2. Three indications of inadequate systems security protection Network layer security
Inadequate systems security protection is primarily aimed at outsiders attempting to gain unauthorized access to the system. It also been used to detect changes in the system's performance indicative of, for example, a virus or worm attack. Attention can then be given to damage assessment or reviewing controls that were attacked. Viruses and worms are forms of malicious code. A virus is a code segment that replicates by attaching copie...

... let you use all the strength features mentioned here. When you get an account or change your password on a system, you should be given instructions on any limitations.
Reminding password: Pick a sentence that reminds you of the password. If you absolutely have to, record it in a secure location. It is probably safer to store a strong password in a place where someone would have to physically break in.
Safeguard Your Strong Password: Do not type your password into un-trusted, unknown, or public computers. Be careful about typing your password into a strange program, web site, or server. Use software that encrypts your password when it is sent over the network whenever possible.
Never use the same password for a risky or casual service. Do not use the same password on an unofficial, entertainment, and off-campus. Replace Your Strong password when it wears out.
Are our passwords secure? (For example, are users required to change their passwords regularly? Are users not permitted to write their passwords at obvious places?)
Description: Generally default factory configurations for appliances and embedded systems contains simple and publicly open passwords and the vendor expect that user should change the password once they start using those systems for personal use. The alert is about the risk involved in keeping these factory default passwords when using the system for personal use.
A big responsibility lies on the customers to protect their accounts from getting stolen by thieves. A part of that is using strong and complex passwords and using different passwords for different accounts. But still, the company can play a significant role in helping the customer protect their accounts by requiring minimum criteria for the passwords. For example, the password shouldn’t match the username, it should include letters, numbers and special characters, and it should be at least eight characters. Also, using double authentication methods for processing the purchases would have protected the

This is only a small part of the prevention of infiltration of your network and computer. If one desires to learn more, go above and beyond and continue to learn on how to keep your network secure.
Remove bathroom locks to avoid accidental locking in. Install secure locks in outside windows and doors, to keep the person from wandering.
Finally, the three-factor authentication deals with biometrics. This is the use of retinal scanning, voice prints, fingerprints, etc. This is one of the most effiecent authentication processes because the major credential is impossible to steal or imitate. This is because is uses the most unique person of a person. Among all the acess controls, fingerprint scanning is commonly used because fingerprints are unique to one individual noone shares the same finger print.
Another important way of making sure that your home is safe is to pay attention to all entry and exit points as well as windows and deck doors. If you live in a complex, pay attention to all stairwells, fire exits, as well as entrance and exit points. Make sure that windows with easy entrance points such as those on the ground floor are locked at all times or for even more sense of security, barred. Also make sure all deck and patio doors are locked unless you are using them. These small steps will ensure that your home is a safer home.
This article examines the use of multiple authentication methods to increase the security of a system. Moreover, with the use of biometric methods, the author seeks to show that authentication can occur continually during the time the resources are being utilized.

This paper includes the comparison between access control models Mandatory Access Control (MAC), Discretionary Access Control (DAC) and Role Based Access Control (RBAC) and explores the advantages and disadvantages of implementing the subjected models. They provides the fundamental policy and rules for the system level access control. . Role-based access control has been presented alongside claims that its strategies and working are common enough to integrate the customary access control models: mandatory access control (MAC) and discretionary access control (DAC).the aim is
"It is a matter of education for the employees to educate them on the hazards and risks," Cunningham said. "There's a policy aspect of it: If you're accessing our financial application, 'thou shalt not use that password for anything else in your life.' And then there are tools you can use to help automate that process for the employees, such as a Password Bolt. Maybe they don't know what the password is, but they can log into the Password Bolt and the passwords are generated for them." All this can be achieved through policies and the policy must be enforced and be audited to ensure adherence to this

How can your password be stolen? And how do you stop someone from stealing your password? Are there levels of computer security? And if there are what are they? All of these questions will be answered and maybe even more.
Detecting ICS cyber-attack is difficult; hence we need Application Whitelisting (AWL). In one of the cyber-attack a malware having 0 percent detection rate compromised 80 percent of the assets of ICS, the antivirus seemed to be not useful in this case. Use of AWL becomes essential since it detects and prevents malware executions. Successful AWL implementation are very few. Systems such as human-machine interface (HMI) computers and database servers, are ideal candidates to run AWL. Operators and vendors must
