Usalama wa Komputa yako

Ingawa mara nyingi tumekuwa tukisikia hakuna usalama wa asilimia miamoja kwenye ulimwengu wa kompyuta,ila kinga ni bora kuliko tiba.

Hebu angalia,wengi wetu tumeweka nondo za kutosha majumbani mwetu huku tukiwa na lundo la mbwa wakali. Ingawa vyote hivi sio kama vitawazuia majambazi kukuingilia,ila inaweza kusaidia kuzuia vibaka wadogowadogo.

 Kwa mantiki hayo,leo hii tutaangalia njia bora za kujikinga na kujiweka katika mazingira ya usalama.Binafsi nimeshasahau mara ya mwisho ni lini kuvamiwa na virusi au minyoo,sio kwakuwa natumia programu za ulinzi zenye nguuvu saaana au ni bingwa sana kwenye masuala ya kompyuta hadi virusi vinaniogopa,bali ninafuata kanuni bora za usalama wa kompyuta ambazo leo hii nitagawana nanyi. Hivyo bila kupoteza muda hebu tuziangalie kwa mapana yake.

 

I.Tumia programu unazozihitaji

 Wengi tumekuwa wahanga wa matatizo ya kompyuta kwa kujisababishia wenyewe,inawezekana kwa kujua au bila kufahamu.

 Kompyuta nyingi zimekuwa zikiathiria na masuala ya kiusalama sio kutoka nje bali ndani ya kompyuta husika. Matatizo haya mengi husababishwa na programu ambazo hazijaandikwa kiusahihi.Chukulia mfano jinsi ukuta wa nyumba unavyoweza kukuangukia na kuvunja vifaa vyako vya ndani au bati ambalo halijagongelewa ipasavyo na kuacha tundu kwenye njia ya msumari na kupitisha maji pindi mvua inaponyesha. Hii ni sawa na hizi programu,kama programu haijaandikwa ipasavyo inaweza kukusababishia matatizo mengi.Sio tu kuhitilafiana na mtambo endeshi(OS) wa kompyuta yako na wewe kuona kama kirusi bali pia inaweza kuacha mianya ambayo wavamizi wanaweza kutumia kuingia kwenye kompyuta yako.

 

Mazingatio.

• 1.Ondoa programu ambazo hauzitumii ili kupunguza uwezekano wa matatizo,wengi wetu tumekuwa na mazoea ya kusimika programu nyingi wakati nyingi kati ya hizo huwa hatuzitumii kabisa,hizi programu hujaza nasafi,kuweka uchafu na hatimaye kutuweka hatiani.

 

• 2.Hakikisha unatumia programu zilizo kwenye wakati,simika maboresho(update) pindi yanapotokea.Nimeshuhudia watu wengi wamekuwa wagumu kusimika haya matoleo mapya kutokana na hofu mbalimbali.Achana na hofu.Maboresho yanakuja kwa ajili ya mambo mema na si kukudhuru.

II.Tumia programu za uhakika

 Je umewahi kujiuliza kwanini natumia programu hii badala ya ile? Ukuaji wa teknolojia umesababisha kila mtu kuja na programu yake,kuna zile za bire,za kugawana na hata zile za bei chee.Sasa sitaki kusema kuwa programu za bei ya juu ndio bora au zile za bei ya chini ni za kukimbiwa kama ukoma,ila wewe kama mtumiaji unatakiwa kufanya kautafiti kadogo kabla ya kuamua kutumia programu fulani. Siku hizi kuna google ambayo inaweza kukusaidia kwa kiasi kikubwa kufanya utafiti na kuangalia maoni ya watumiaji juu ya programu husika.

 Kwa kufanya hivi itakusaidia unapata programu ambayo inakidhi mahitaji yako huku ukiwa salama.Mfano mzuri binafsi sijawahi kutumia Windows Vista,kwani kipindi natumia Windows XP na kutaka kuhamia kwenye mtambo mwingine nilifanya tafiti na kuona watumiaji wengi wakilalamikia windows Vista hivyo niliamua kuachana nayo,habari njema ikaja na Microsoft wakaamua kuiondoa sokoni na kuleta Windows 7 ambayo ni kipenzi cha wengi. Hivyo TAFITI TAFITI TAFITI.

III.Hakikisha unajua nini unachokifanya

 Wengi wetu tumekuwa wahanga kutokana na kukubali kiholela au kufanya mambo tusiyoyajua.Labda nikupe mfano mmoja wa mtu wangu wa karibu ambaye aliwahi kuvamiwa na na hizi programu za matangazo(Adware).Yeye alikuwa alifungua tovuti moja mara akaona ujumbe unasema kompyuta yako ipo hatarini hivyo bonyeza hapa ili kutatua.Bila kujua anachokifanya akabofya na kujikuta ameshaingiza madudu kibao.

 Hivyo kuwa makini kila unapokubali ujumbe wowote.Hakikisha unajua unachokifanya.

Hayo ni mabo machache ambayo unatakiwa kuzingatia ili kuhakikisha unakuwa katika mazingira salama na yenye kinga bora.

Look Inside The US President Car (Cadillac One Limo) in Dar es Salaam Tz

 

 

With its tall roofline, obviously thick skin and fender-mounted flag stanchions, there's no mistaking the president's new limousine for any other stretched Cadillac DeVille. If you're still not sure, read the license plate.

On the final Monday of Bill Clinton's presidency, the White House and the chief executive prepared for a five-day visit with an imposing visitor, one that would soon become a trusted regular in George W. Bush's administration. No, this was not a foreign dignitary or an adviser. This was the new presidential limousine.

While the car's official public debut was the morning of Jan. 20, when both the old and new presidents shared the back seat, Secret Service spokesman Jim Mackin said, "President Clinton got to break the car in because new White House vehicles are put into service as others are taken out. Had this car been ready to use in November, or even August, we would have used it then."

Cadillac echoed this matter-of-fact, government-contract tone when the carmaker announced that it secured the commission of the newest presidential limousine through a standard government bid process.

Though the process of getting the job may have been mundane, the car itself is not. As you might expect of a vehicle that could be thought of as the roadbound equivalent of Air Force One, this is a very special automobile. And, though it may have started life as your uncle's Cadillac DeVille, it's one of a kind.

Of course, given the need for maximum security, no one—from Cadillac or the Secret Service—will tell exactly how this car differs from other Cadillac DeVilles. Even basic technical details like exterior dimensions and curb weight are classified. But, Cadillac does admit that the car is equipped with such enhancements as an integrated 10-disc CD changer, a foldaway desktop and reclining rear seats with massaging, adaptive cushions.

Regardless of the secrecy surrounding the car's specs, even the most casual observer can see that this Cadillac is a rolling fortress. Compared to previous presidential limousines, this DeVille is clearly a protective conveyance and not simply a parade vehicle. The car's small backlite, thick A-pillars and heavily armored appearance announce its purpose.

We do know that this Cadillac is less of a Caddy beneath its bulletproof skin than Air Force One is a basic Boeing 747. Insiders at Cadillac say this limo "is a completely unique vehicle with no shared technology, design or learning passed between it and any production vehicle."

An examination of its exterior suggests that the only stock components are the headlights, taillights and wreath-and-crest emblem atop the grille. Like DeVilles at your Caddy dealership, this one has Night Vision--but the camera has been moved from its spot in the middle of the grille to an undisclosed location. And, the drivetrain behind the presidential grille isn't the Northstar system. Most likely it's an all-wheel-drive setup based on what's underneath a Cadillac Escalade, with some intense modifications.

Note that even the standard DeVille's flush-style door handles have been replaced by a loop-type design apparently borrowed from the 1992-99 generation Buick LeSabre, providing added leverage for opening the extra-thick, heavy doors and doubling as grab-handles for the Secret Service agents running alongside the car.

Every inch of the limo's metal skin is backed by military-grade armor, which offers the highest level of protection with the least weight and bulk penalty. The car's windows—which do not open—are actually transparent armor. All the car's armor is at least 5 in. thick, giving the president maximum protection in the event of any attack. The interior is also environmentally sealed to protect the occupants from chemical and airborne germ-warfare terrorism.

Careful study shows that the wheel openings are larger than stock to accommodate the size of the Goodyear run-flat tires. The front fenders, which carry the flag stanchions, have small spotlights to illuminate the flags. The car's front bumper houses foglights and special flashers--a red one on the driver's side, white or clear on the passenger's side. Connected to the trunklid are five antennas.

Inside, there is room for six people to join the president, all on leather seating. Two sit up front, flanking a console-mounted communications center. In back, behind a glass partition, there are three rear-facing seats with cushions that can be folded up separately against the partition. The president and another passenger sit in the individually reclining rear seats.

A folding desk separates the two rear seats, and storage compartments in the interior panels contain communications equipment. The presidential motorcade includes a special rolling communications center, so the limo need not carry as much communications equipment as Air Force One. Since the glass surrounding him is so thick, blocking out most natural light, the president gets needed light from a fluorescent halo lighting system in the headliner.

And naturally, the president has his own switches for the climate-control and sound systems.

After all, presidential comfort is as important as presidential security.


With 5 in. worth of ballistic armor under its skin, and added height and length, the presidential limo tips the scales at close to 4 tons. It's probably based on a modified Escalade platform, riding on run-flat tires. The dark leather interior is environmentally sealed against chemical attack.
