COMPUTER SECURITY - PART 2

To understand more about the Computer Security, we have to go deep in other areas and evaluate and consider the RING OF SECURITY AND COMFORT. What does this mean?


Think of yourself and analyze everything around you, now think what are the security levels which surround you, analyze what are your strengths and weaknesses and what weaknesses or vulnerabilities when you are attack. This analysis is beyond what you think and see in our daily basis, we consider this is by done ok. What I mean is:

Now, in a technological way… we can switch to computers, phones, tablets and others and review the following points:


SYSTEMS AT RISK
Computer security is critical in almost any industry which uses computers. Currently, most electronic devices such as computers, laptops and cellphones come with built in firewall security software, but despite this, computers are not 100 percent accurate and dependable to protect our data.

There are many different ways of hacking into computers. It can be done through a network system, clicking into unknown links, connecting to unfamiliar Wi-Fi, downloading software and files from unsafe sites, power consumption, electromagnetic radiation waves, and many more.

However, computers can be protected through well-built software and hardware. By having strong internal interactions of properties, software complexity can prevent software crash and security failure.


ELECTRONIC MONEY ON SHOPPING WEBSITES
Web sites and apps that accept or store credit card numbers, brokerage accounts, and bank account information are prominent hacking targets, because of the potential for immediate financial gain from transferring money, making purchases, or selling the information on the black market. In-store payment systems and ATMs have also been tampered with in order to gather customer account data and PINs.


CONSUMER DEVICES
Desktop computers and laptops are commonly infected with malware either to gather passwords or financial account information. Smart phones, tablet computers, smart watches, and other mobile devices such as Quantified Self devices like activity trackers have also become targets and many of these have sensors such as cameras, microphones, GPS receivers, compasses, and accelerometers which could be exploited, and may collect personal information. WiFi, Bluetooth, and cell phone networks on any of these devices could be used as attack vectors, and sensors might be remotely activated after a successful breach.

 
LARGE COMPANIES
Large corporations are common targets. In many cases this is aimed at financial gain through identity theft and involves data breaches such as the loss of millions of clients' credit card details by Home Depot, Staples, and Target Corporation. Medical records have been targeted for use in general identify theft, health insurance fraud, and impersonating patients to obtain prescription drugs for recreational purposes or resale.


GOVERNMENT
Government and military computer systems are commonly attacked by activists and foreign powers. Local and regional government infrastructure such as traffic light controls, police and intelligence agency communications, personnel records, student records, and financial systems are also potential targets as they are now all largely computerized. Passports and government ID cards that control access to facilities which use RFID can be vulnerable to cloning.


INTERNET OF THINGS AND PHYSICAL VULNERABILITIES
The Internet of Things (IoT) is the network of physical objects such as devices, vehicles, and buildings that are embedded with electronics, software, sensors, and network connectivity that enables them to collect and exchange data - and concerns have been raised that this is being developed without appropriate consideration of the security challenges involved.

In particular, as the Internet of Things spreads widely, cyber-attacks are likely to become an increasingly physical (rather than simply virtual) threat. If a front door's lock is connected to the Internet, and can be locked/unlocked from a phone, then a criminal could enter the home at the press of a button from a stolen or hacked phone.

REASONS TO REPLACE YOUR COMPUTER FAN AND HEATSINK

REASONS TO REPLACE YOUR COMPUTER FAN AND HEATSINK A computer's fan and heatsink are two of its most important components. The primary role of both is to cool down the processor and keep it from overheating. A laptop or notebook does not have to be outside in hot, humid weather to overheat. In fact, even if a computer is kept away from extreme heat altogether, it can still overheat. That is because a computer's processor is responsible for processing information and giving instructions to other components in the computer. A processor can get very busy as a result, especially when it is running multiple programs simultaneously. As a result, it heats up, and if there is nothing to cool it down, it can malfunction and break down, costing the owner hundreds or even thousands of dollars. This is why a good fan and heatsink are necessary. The more demand placed on the processor, the more effective the fan and heatsink must be. This guide identifies five issues...

LET’S TALK ABOUT PC AUDIO SPEAKERS

LET’S TALK ABOUT PC AUDIO SPEAKERS Computer speakers are one of those PC accessories that are almost essential; and you can spend anywhere from $10.00 to $1,000.00 for quality PC speakers, depending on your budget.   There are tons of tons of speakers with features and different prices as we know. But as I always say: WHAT and HOW is what I am looking for. For sample: I have this one in my office and works properly, the only disadvantage is that has no RADIO and only can be played with micro SD and plugged to my computer. And only pay like $20-$25. USB charged and the battery longs for 6 hours. https://www.energysistem.com/en/products/music_box/music_box_series_/42198-energy_mini_music_box_z100_r_black Here there is some thoughts and share some personal ideas about this topic. I enjoy listening to music a lot, and because my computer is the main source for my digital music collection, a decent speaker system is essential. Expensive is not a...

LET’S TALK ABOUT - NETWORK FORENSICS

LET’S TALK ABOUT - NETWORK FORENSICS BASIC CONCEPT Network forensics is a sub-branch of digital forensics relating to the monitoring and analysis of computer network traffic for the purposes of information gathering, legal evidence, or intrusion detection. Unlike other areas of digital forensics, network investigations deal with volatile and dynamic information. Network traffic is transmitted and then lost, so network forensics is often a pro-active investigation. Network forensics generally has two uses. The first, relating to security, involves monitoring a network for anomalous traffic and identifying intrusions. An attacker might be able to erase all log files on a compromised host; network-based evidence might therefore be the only evidence available for forensic analysis. The second form relates to law enforcement. In this case analysis of captured network traffic can include tasks such as reassembling transferred files, searching for keywor...
