A Great Video On Hacking And Protecting Yourself

I like to post these sorts of videos because I know people will watch them and I know sometimes a video will sink in better than some jumbled mumbo jumbo words of mine.


Steps You Can Take To Eliminate Computer Security Risk

spyware234Computer security is one of the biggest issues facing us these days.  Hacking has become a rampant problem, and one of the worst things that one can do is leave their data unprotected.  So much of our daily lives are conducted on the internet nowadays, and more and more of our personal information is flying around out there in the ether, waiting for some hacker to get their hands on it.  This is why there is a constant fight between good and evil: white hats vs black hats.  And then what will you do with the grey hats in between?

Anyway, there are definitely some steps you can take in order to mitigate your risk of computer security breaches.

One of the fist things that I suggest to people is to ensure that their software is up to date at all times.  This means activating automatic updates even if you don’t like them.  Yes it’s annoying, but you’ll never be overly vulnerable to any security holes that might be in the software.  Most of the time patches and updates are there to fix security holes in software, and if you’re not updating you’re leaving yourself WIDE open.  This is why it’s very important to turn on those updates even if you find it highly annoying.

Another thing that you can do to ensure that you’re protected is to frequently sweep your computer for malware.  You can use one of a few good spyware removers such as Spyhunter 4 or Malwarebytes.  These programs are great and there are several great reviews of them out there online so you can pick and choose which one would be best for your situation and pricing.

In addition to protecting yourself from break-in’s you should also back up your data every day.  This is especially true if you have non-replacable data on your computer.  Think about ransomware, for instance; would you rather just reboot your computer from a saved backup, or fork over 10,000 in order to unlock your computer from the clutches of some evil malware or ransomware?  The choice is yours – ensure that you’re running an adequate backup program and stay up to date on any updates.

One other thing that you can do to ensure that you’re on top of things is to bookmark and read security blogs.  I like reading Wired Threat Level because they always seem to have interesting stories and topics.  Another great blog is Krebs On Security.  These two are my favorites – they almost read like a crime novel!  They are also very good at helping you to stay up to date on the latest threats so that you can be on the lookout for them.  Remember: knowledge is power when it comes to digital security and the more you know about scams the faster you can spot them in the wild.

Last but not least – ensure that you’re running an adequate antivirus software program.  YES this is still necessary.  Some people I know seem to think that there is no need for these sorts of programs anymore….like they are out of date and something that ended with the 90’s.  NOT TRUE!  You should always have antivirus software running on your computer.

The History Of Digital Storage Media

This is a followup post to my last post about the history of tape and floppy drives.  I really find the history of digital storage media to be quite interesting because of how far we have come in such a short amount of time.  It will be even more interesting to see where we go from here as well.


Old Style Of Backup Systems

tapedriveBack in the day when data backup only consisted of kilobytes, the backup systems were much more rudimentary.  Who remembers tape drives?  Seems like a relic of the past, right?  Well, it wasn’t so long ago that tape drives were the latest and greatest, costing thousands of dollars.  This excerpt from an article from 1987 highlights just how far we have come in terms of data storage.  A simple smartphone that we now take for granted would have been unthinkable back in 1987.

Tape cartridges in 1/4-inch format, most common for microcomputers, also come for 3 1/2-inch and 5 1/4-inch start-stop, streaming and floppy-like drive units.

Start-stop devices record and access best in file-to-file mode. Streaming units are good at image backup, and floppy-like devices eliminate the need for a separate tape controller but require a formatting procedure that takes 40 minutes or so.

Many microcomputer installations need access to mainframe-resident data. They often resort to traditional 1/2-inch reel-to-reel magnetic tape systems. However ungainly and costly these devices may be, they transfer data efficiently between mainframe and microcomputer. Costs are in the $3,500 range.

The reel-to-reel units dwarf a standard desktop system, and there are few alternatives. However, with growing acceptance of IBM’s 3480 tape cartridge, the same standard of interchangeability that now applies only to tape reels may become available in a smaller configuration.

Vendors are working to supply a 5 1/4-inch drive form factor. The 1/2-inch cartridge is expected to be available by the end of August, with interfaces for small systems.

Initially aimed at super-microcomputers, these drives eventually will provide capacity between 250M and 300M for traditional microcomputers. The switch will give microcomputers a more cost-effective way to take advantage of the volumes of data generated by mainframes.

In the meantime, the 1/4-inch tape DC600-style cartridge is used by microcomputers. Widely available in the 5 1/4-inch form factor, 1/4-inch cartridge drives have become a primary source of backup.

DC2000-type drives, growing in popularity because of their smaller size, adapt to the space constraints of the desktop. Measuring 3 1/4 by 2 1/2 by 3/8-inches, about the size of the familiar audio cassette, these miniature cartridges squeeze 40M onto a 20-foot piece of 1/4-inch magnetic tape. Data is written onto 20 or 24 tracks positioned across the width of the tape.

Depending on whether they adhere to QIC-100 or QIC-40 standard specifications, these drives use a floppy disk interface to transfer data at floppy speeds, or they connect to a dedicated interface that allows faster transfer.

Different Interfaces

So-called floppy tape devices run the tape drive as if it were a DOS disk and operate from the floppy disk interface within the microcomputer.

In the 10M to 20M capacity range, DC1000 catridges, although about the same size as the DC2000, record on .15-inch tape. When used through the system’s floppy disk controller, they are the lowest-cost alternative with sufficient capacity to handle most low-end backup storage needs.

For users who must move data between microcomputers and larger but dissimilar computer systems, it is necessary to go to a network or put the data on a floppy and walk it between systems, according to Larry Hemmerick, director of planning for Cipher Data, San Diego. If volume storage or volume data is involved, the user often must resort to nine-track tape.

For PC applications that absolutely must be interchangeable with host systems, a nine-track tape is the solution. It is expensive but interchangeable.

Because the microcomputer environment has no tape tradition, there is no recognized procedure for performing backup. According to industry pundits, “There are only two types of people in this business: Those who have lost data and those who are going to.”

Two factors make or break tape backup: speed and ease of use. Software affects both. On the issue of data security, the amount of time to restore data to the system is irrelevant because, no matter how long it takes, that time is less than the time needed to rebuild an entire crashed disk.

A user who buys a 1/4-inch drive should realize that its performance is less than that of a reel-to-reel drive, with a price differential of $2,000 compared with $50,000. Backup time, throughput, error detection and correction capability are not equivalent. The 1/4-inch works, it just doesn’t work as well.

Rotating media devices offer a better, though more expensive, solution where data protection is important. Fast restoration of data also is essential after system failure or when on-line access to stored data is a benefit.

Disk drives access data faster than tape because their moving read/write heads minimize the distance traveled on the disk surface. Tape devices, on the other hand, have a fixed head past which the tape moves to reach the desired location. Even at 90 inches per second, it takes some time to move 200 to 600 feet of tape.

Although integrating rigid cartridge products into a system is more expensive than using tape products, it is the only way to provide functions beyond backup, according to Tom Desmet, director of product planning for Magna Computer Corp., Manchester, N.H.

A removable Winchester disk allows the user to remove the data and put it in a secure environment. Because encryption and password protection can be provided on the cartridge, the disk will be unusable on any other machine or by anyone lacking the password.”
