Data Security and Integrity: Software and Physical Restrictions

delay of Contents Page Introduction Introduction Maintenance of entropy surety and integrity in reference to Softw be Access Restrictions These are inserted for the purposes of defend computer software package. A fewer forms of software irritate restrictions are as follows Passwords Definition -A string of characters that allows adit to a computer, interface or system. How does it answer in securing information and maintaining its integrity? When a person creates a watchword for inlet to a computer, folder, program etc. they are creating a codification that must be implemented every time they wish to access the software. This means that if any(prenominal) unknown or unauthorised personnel were to walk out on to view the material and were unaware of the password then they would be ineffective to do so, and then securing the entropy.The integrity of the selective information is in any case highly defend when using a password beca manipulation if any unknown or unau thorized personnel attempt to access any selective information that is password protect without knowing the password, they leave be denied access. Thus the info plentynot be neutered in any way and its trus twainrthiness would remain the same(p). * Data encoding Definition -This is the encoding (encoding) of data for security purposes. How does it support in securing data and maintaining its integrity? By encrypting, we change the original plaintext version of data into ciphertext, which is an undecipherable format that leave alone protect against unauthorized parties.Only those who possess the key to creation the algorithm that will trace the data, hence making it readable, can access it. A higher bit encryption is much more proficient than a lower bit encryption, for example a 256 bit encryption is much more secure than a 128 bit encryption because a hacker will posit to try out more possibilities when difficult to breach the encryption. Once data is encrypted the integrity of it is safeguarded just as farsighted as it isnt breached by a hacker or accessed by any unauthorized party who somehow got the key to the algorithm, and was able to decrypt the data. Virus Protection Definition -This is the protecting of a system from a file that replicates itself without the consent of the user. How does it help in securing data and maintaining its integrity? regular anti-virus software protects a computer system from viruses, Trojan horses, worms etc. by means of routinely or manually scan files and programs to check for the same malware and if any malicious content is found, it either notifies the user of its presence and suggests steps that can be taken to remove it, or automatically starts doing so by itself.Any malware that is located early enough by anti-virus software can usually be removed before it can cause any irreversible damage to data. Though there are viruses that can take effect almost immediately and corrupt data very readily bef ore the virus auspices can take action or even notice it. In this case having better virus protection software is necessary. * Firewall Definition -This is an integrated collection of security measures designed to save unauthorized electronic access to a profitsed computer system.How does it assist in securing data and maintaining its integrity? A firewall protects a computer system or network from any malicious activity from the internet, for e. g. hackers, viruses and Trojan horses. They do so by filtering any incoming packets of data to decide which data will be let through the firewall and which will be discarded. This means that data already on the computer or network will be better protected against hackers, viruses etc. and any incoming data will be clean i. e. without any malicious software attached.Firewalls assist in maintaining data integrity by its ability to filter data. As colossal as the firewall prevents malware from entering a computer system or network the data will not be adversely affected thus maintaining its trustworthiness. Physical Access Restrictions These consist of biometric systems as well as otherwise forms of physical access restrictions that are used to protect data. A few forms of physical access restrictions are * Voice Recognition Definition -This is a device used for the identifying of individuals by the sound of their voice.How does it assist in securing data and maintaining its integrity? Voice Recognition is a biometric system i. e. it identifies individuals by a unique human characteristic, their voice. The way this aids in protecting data is as follows if soulfulness wishes to gain access to something, in this case data, they would need to verify to a computer that they are permitted to view or command the data by speaking. If they are not registered to gain access to the data then the computer would deny them the ability to view or interact with it, thereby maintaining its integrity.If the speaker is registered w ith the voice recognition, then it would grant the speaker access. This allows data to be viewed by authorized personnel only. Voice recognition is considered to be more secure than passwords because of the fact that, instead of depending on a occult string of characters to gain entry to the data, it identifies them by their voice hence removing the opening night of guessing. * Retinal Scan Definition -This is the biometrical identification of individuals by scanning the retina of the eye.How does it assist in securing data and maintaining its integrity? A retinal scan operates in like manner to voice recognition, this is because they are both biometric systems. The way this assists in securing data is as follows The retina of the eye, which is unique to everyone, is scanned. The computer can identify people by the use of camera technology which can differentiate individuals from one another because of the subtile differences in their retina. If the person is recognized as autho rized personnel, then they are allowed to view the data.If however, they are not authorized to view the data, they will be denied access from doing so as well as from manipulating it, this allows for the safekeeping of data and the maintenance of its integrity. * Fingerprint Recognition Definition -This is the automated method of confirm a match between two human fingerprints. How does it assist in securing data and maintaining its integrity? This is another biometric system, and the most popular one at that. Fingerprint recognition is widely used for the protection of data because of its truth and dependability in identification.Just as there are no two people who share the exact same voice or retina, there are no two people who share the exact same fingerprints. Because of this, fingerprint recognition can be used to allow someone access to data once the person accessing the data places his finger onto the scanning device. If his fingerprints match those that are registered then he/she is allowed access to the data, otherwise access will be denied. * Fireproof Cabinets Definition -A fire resistant water closet/box which can house computer hardware that contains data. How does it assist in securing data and maintaining its integrity?Data is located inside software, however software cannot function without hardware. Therefore, in order to protect the software which houses data, we must also protect the hardware which houses the software. Fireproof cabinets are an excellent way of doing so. They assist in securing the hardware by allowing it a special area so that it is not lost or misplaced. Also, if there is a fire which could potentially be disastrous, the fire resistant cabinets will protect the hardware from macrocosm destroyed while also indirectly protecting the data.
