Our devices. Whether it’s phone calls, laptop, or tablet; occasions are it contains( or at least thisaccess to) some somewhat feelings information.Think about it. How do you access your bank? Where are your family photos? Yourpersonal themes? What about your work? If your manoeuvre getshacked, that info could be destroyed, stolen, or published for the whole world to see. I’m going to give you some tipsto help prevent that happening. Welcome back to The Pro Tech Show. Thisvideo is the second in a series of “How to Protect Yourself From Hackers”.We’ve already covered your online chronicles, and now we’re going to talkabout your devices. I’m going to start by making sure wehave the basics submerge, and then we’ll move on to a few gratuities that may beless obvious. Tip number one: always use protection.Yeah, you heard me … but I’m talking about anti-virus. Anti-malware might be moreaccurate, but most people don’t care about the mark, so I’m going to stick with the “V” word for this video.Sounds obvious, right? Well, sometimes it can be the case that the more you are familiar with, the lazier you get.Some tech-savvy beings will disable their antivirus, reflecting it slows downtheir computer; but hey, it doesn’t matter because thebest antivirus is common sense … That’s actually genuine, to a point.Educating yourself will cut down your chances of encountering malware morethan any antivirus will. The difficulty is it doesn’t increase yourchances to zero, and once you encounter one you’re now wide open. Even if youonly trip trustworthy websites, you can’t guarantee that one of those goodwebsites won’t get breached themselves and have malware embedded on their sitewithout their lore. If it’s using a zero-day exploit, there’sbasically good-for-nothing you can do. What if you use your laptop on public wi-fiin a coffee shop? Do you trust everyone else’s design in that coffee shop? You might think you know better, but do you think all of the other customersknow better more? Because if one of them is infected, thatmalware is going to try and exploit its mode onto your computer.I was once sent to help an organisation that was struggling to contain a malwareoutbreak.They knew how it started: someone broughtan polluted laptop back from a foreign errand and plugged it into the network.They knew how it spread: it was exploiting an unpatched vulnerability ina Windows assistance. They’d patched the vulnerability, incapacitated the service, and extend removal implements on every machine on the network; but it exactly hindered reappearing within minutes.Do you wanna know why? Two of the elderly IT guys had incapacitated theirantivirus, because “they knew better”. Well, guess what? Theircomputers went fouled, they didn’t realise, and because theywere also logged on using admin histories their computers were sat thereinstalling malware on every invention in the network, no exploit required. This was a network withthousands of users. Don’t be those guys. You don’t need to spend money on this ifit’s for personal use.A much of computers come with some nagwaretrial rubbish set that hassles you for fee, but it’s just notnecessary. There’s nothing wrong with a paidproduct, but there are plenty of free options, and Windows comes with Defender constructed right in. Tt’s not about having the best or mostexpensive make. Merely use something. If you’re running abusiness, though; you probably do want to get your wallet out for centralisedmanagement and reporting.Free is all well and good until you’vegot a originating collecting of maneuvers that you need to checkare up to date and healthy every single day.That’s going to become a waste of time pretty quickly, so you’ll want to pay forthe automation. And before you say “buy a Mac”, know thatMac malware is currently growing at a faster charge than Windows malware.Admittedly it’s also typically less dangerous, but it’s still a good thought toprotect yourself.Macs aren’t magically immune. The simplefact is that the more popular a scaffold becomes, the more it’s going to do targeted. As Macs grow in vogue this is going tobecome more of an issue. Moving on from antivirus, let’s talkabout your firewall. I’m talking about the host-basedfirewall on your design , not your system firewall or the one built into yourrouter.Firewalls get misrepresented a lot on Tv, but a basic firewall is not that complicated.Its profession is to block network connections to your maneuver, unless you’ve chosen toallow them. As two examples: if you want to streamvideo from your laptop to your Tv, your firewall needs to allow the Tv toconnect to the media on your laptop. If you go to a coffee shop the firewallshouldn’t allow other customers to connect to your photos or your papers as well. Almost any modern design will come witha firewall enabled by default. The question with firewalls is much thesame as a problem with antivirus: a lot of people turn them off! Sometimespeople do this at home to try and work around an issue with video games, but this is actually a much bigger problem in the corporate macrocosm than itis for home users; and it’s all down to laziness. Here’s atypical scenario: an IT admin is rolling out a newapplication, and for some reason it isn’t working.As a troubleshooting stair they incapacitate the firewall on their measure computer, andsuddenly it works.Right. So now they know the firewall isblocking the employment, but firewalls are a network thing andthey’re an apps being, and they need to get this application flattened out today.They could figure out what configuration is necessary to start the firewall playnice, but that would take too long, so instead theyroll out the lotion anyway and disable everyone’s firewall.This is a temporary measure, of course. They’ll go back andfix it last-minute … Yeah, right! Any IT pro will tell you thatthere’s no such thing as a temporary fix. Once something’s working, focus shiftsthe next urgent trouble, and the temporary repair becomes…Kind ofpermanent. This is how most incapacitated firewalls I come across get that behavior. The problem is that when someone doesget around to “ve got something” about it, that could be six months or a year later.But what about all the apps ought to have deployed since? Did any of them have aproblem with the firewall? The issue now is: nobody knows, becausethe firewalls were incapacitated and those apps were never experimented with the firewallturned on. This is the situation a lot of IT prosfind themselves in. If they enable the firewalls now, theyhave no idea what might transgress. Look. The space to avoid this is obvious.Don’t take shortcuts. Do it properly the firsttime.Chances are though that this wasn’t yourfault. Maybe you precisely acquired it. If you are in that situation then thebest time to tackle it is now. The difficulty isn’t going to go away.The longer you leave it, the worse it gets, and the more risk you expose yourbusiness to. I’ve heard some IT pros say that itdoesn’t matter if firewalls are incapacitated, as long as the invention has antivirusinstalled. This is nonsense.If your firewall isdisabled, malware doesn’t need to foul yourdevice – it can merely give the data over the network.In knowledge, there’s a good chance it can connect your device over the network andtell it to switch off its antivirus before it tries to infect it.Guys: remote handling was a matter, and the bad people can use it too.Let’s look at WannaCry for your illustration: it started pogrom in 2017. Most of the feigned machines had antivirus installed.Despite what was widely reported, its spread had very little to do withWindows XP.In fact, the initial account of the WannaCry malware wasn’t even compatible with Windows XP! The initial spread happened primarily because of firewalls had been switchedoff or misconfigured, allowing the malware to exploit a flawin a register sharing service that should never have been exposed to the internetin the first place. Make sure your firewall is enabled. Againyou don’t need to buy anything – the one built into your invention issufficient.

You don’t definitely need to be on thelatest version of everything, but you do need to be on a version that isreceiving security updates; and you need to install them.This meansyour operating system, as well as all of your applications. Someof these will stimulate you when revises are available, as long as you’ve got theoption enabled. Others require a little more manualeffort. Every security update has a purpose – a flaw that it defines. As soon as it gets exhausted, the bad people are going toanalyse the update and try and figure out what blunder it fixed.Then they’re going to try and employ that flaw on any computers that haven’tbeen informed. It’s mostly an forearms scoot, and youdon’t want to be the loser. The good report for residence customers is thatit’s pretty easy to keep your computer up-to-date, and I’m going to share something that will help with that. For businesses…well trying to keep hundreds or thousands of computers up to date is awhole different challenge; but “youre supposed to”, because if you look atthe high profile hacks that touched the word, they quite often start with out-of-datesoftware.Keeping track of all the updates on your computer can be a majorpain, but you can use a tool to help you. Forbusinesses, there are a lot of options out there and i don’t have time to coverthem all. You will want to look at a business-focused solution though to give you centralised monitoring and management.For home users, make sure you’ve got your built-in automated revises enabled( formost of you this is gonna be Windows Update ,) and there’s a handy little tool I’lllink in the description called Patch My PC. It’ll scan your computer and tell you what needs to be updated. There are more comprehensive solutions, but this one’s easy to use; and it’s free. It extends the most common software, which is what malware authorsare going to be targeting. Those gratuities will help prevent your devicegetting hacked over a system; but what if somebody comes physical access to it? The most obvious case being if it was stolen, but also maybe if you sell it onwhen you’re done with it.The first thing you need to make sureyou’re doing is using a login. Whether that be a PIN, password, orfingerprint; make sure that somebody can’t simply pick up your manoeuvre andaccess your data. Maybe don’t use one of those structure open things where youswipe over the dots … They’re not great. Try it yourself – unlockwith a structure swipe, then switch off the screen and nurse your telephone up to awindow. Occasions are you can still construe the swipemarks left on the screen. Oops! This might stop a informal robber, butthere’s a saying in cybersecurity that if a intruder can get physical access toyour computer, it’s no longer your computer. All thefirewalls and passwords in the world mean nothing if i can snatch out your harddrive and read it in a different computer; or plugin a USB drive and overwrite your password.There are a few things you can do about this, but the most important one isencryption.If you encrypt your drive, then it ishighly unlikely anyone will be able to simply yank it and speak your data.There are ways of breaching certain types of encryption, and if you’reworking on something top secret you would need to be aware of that, but your median thief or even your median IT professional is not going tohave the consultant talents or material to do that. A mas of consumer devicesthese days come with support for encryption baked in.If yours has it, turn it on. If your computer doesn’t have an option forencryption out of the box then it’s still possible to use freetools to encrypt your drives. Exactly be aware that the user experiencemay not be as huge. If you’re a business, then it’s honestlynot even a question worth discussing.If “youve had” data moving around onunencrypted maneuvers you may as well really publish that data on the internetyourself. Encrypt it! When you come to sell ordispose of your manoeuvre, make sure that the data on it has beendestroyed. If you’re a business with a lot of maneuvers need to be addressed, then thereare firms who will do this for you and verify the destruction.If you’re a dwelling customer, it’s probably going to be up to you.There are so many manoeuvres out there that I don’t have time to properly cover theoptions. If it’s a phone, you’re typically lookingfor a factory reset option. If it’s personal computers then you either want a securewipe curriculum, or you can physically destroy the driveitself. The proper way to do each of these is going to dependon what various kinds of drive you have, and whether you require the invention to be usablewhen you’re finished.Not all software is appropriate for alltypes of drive. I’ve got enough to cover this videoalready, so what I’ll do is I’ll create a follow-up videoshowing you how to figure out what type of drive you have, and how you can wipeit securely. If that that video has already gone live by now I’ll pop a card up in this corner. If not, subscribe and turn onnotifications to find out when it’s up. For now, exactly be aware that simplydeleting the registers doesn’t actually destroythem; and the data can be easily recovered squandering readily available tools.OK. We’re nearly there. Last flake of suggestion. Alwayshave a backup. You can take all the prudences you want.Something can still go wrong; but if it doesn’t, you should have a backup anywayin case your design fragments or does stolen.A plenty of malware these days is what you’d call “ransomware”.It encrypts your data, then expects money to get wise back.Obviously, you’d prefer not to do that. It costs money.If you do compensate, there’s no guarantee you’ll actually get your data back.Even if you’re doing well enough that the money isn’t an issue, and they dogive you all your enters back as predicted, you’ve still money criminals.I’m nothere to reviewer for that. I know it’s a difficult position if it’s the only wayto get your treasured rememberings back, or save your business; but we can all agree that you’d rather not be in that position in the firstplace. If you have a backup then you can simplygive them the midriff paw, and rehabilitate your own documents; but it needsto be a proper backup. A lot of computers get sold to consumerswith an included backup program; and a good deal of these are a terminated imitation, because they back up your laptop…To your laptop. What’s the point of that? If your laptop gets trashed, your backup is junked too.Your backup needs to go to a physically separate maneuver to be worthanything. That could be a USB drive or mas storage, or for a business it could be an encrypted backup videotape that getscollected and accumulated off-site. The important thing is that it needs tobe offline from the computer or network you’re backing up.If you can get to the backup from your computer, then the bad chaps can destroythe backup from your computer.For a USB drive, this means you unplug itafter each backup is complete. For network storage … well you probablyneed an extra offline tier as well, or at least some practice to make it invariable evento an administrator. Of track the most secure machine in theworld is worth nothing if your chronicle itself has been compromised.That’s why I made this video up now, which is all about protecting youraccounts from intruders. If you’ve already watched that, then howabout watching this video down here instead? If you concluded this one useful then cause it like before you go, and don’t forgetto subscribe for future videos. Thanks for watching, guys.See you nexttime !.
