Auto update what does a firewall and so on

Automatic update: You can keep the latest system patches in a timely manner, and also fix some minor problems The role of the firewall, and some professional The role of the firewall 1Packet Filtering Is it a firewall with packet filtering?

Yes, that's right! According to the definition of a firewall, any method that can effectively block unauthorized connections to the network is considered a firewall. In the early days, firewalls generally used the conditions set to monitor the characteristics of the packets that passed through to decide whether to allow or block, and packet filtering was a very important feature.

Although there are many new concepts put forward in the development of firewall technology, packet filtering is still a very important part, just as the Layer 4 switch is still the first to have the basic function of a fast packet. With packet filtering, firewalls can block attacks, prohibit external and internal access to certain sites, and limit the number of traffic and connections per IP. 2.

Transparency of the package** In fact, firewalls are generally erected in front of the servers that provide certain services. If it is represented in a schematic diagram, it is server-firewall-guest. The user's request for access to the server and the information fed back to the user by the server need to pass through the firewall, so many firewalls have the ability to gateway.

3.Blocking external attacks If a user sends information that is not allowed by the firewall settings, the firewall immediately blocks it from entering the server behind the firewall. 4.

Logging Attacks If necessary, the firewall can actually record all the attacks, but for the sake of efficiency, the current task of recording attacks is generally done by IDS, which we will mention later. Installing anti-virus software can kill viruses and check viruses, but it is not 100% new mutant viruses, or new viruses. Antivirus software doesn't always work completely!

Trouble, thanks!

First, automatic update refers to the system automatically downloading new system patches from Microsoft Official**. (The main thing is to patch vulnerabilities and make the system more secure, after September 20th, Microsoft started the black screen program, which is to check for non-genuine versions by new patches.) So it's still not updated.

Second, the firewall can block some unknown programs and signatures from entering the computer, when you run a program for the first time, it will block the prompt for you, and you can choose to unblock and other options. (It's not of much use, I'm usually closed) Third, you can't 100% defend against viruses, because in many cases, there are viruses before the prevention and update of antivirus software. (Just be careful about surfing the Internet and installing the program, and there is no problem with the general software from the regular **** theory.)

The file filtering and detection of antivirus software will slow down your machine, so as long as you maintain good usage habits, it is recommended to use 360 Security Guard).

Turn off firewall and automatic update in computer management, take win7 as an example to do as follows:

First, in the Start menu in the lower left corner of the taskbar, click [Control Panel], and then click [System and Security] in the control panel.

<>1. Turn off automatic updates.

1. Under Windows Update, click [Enable or Disable Automatic Updates];

2. Change the setting to [Never check for updates], click OK.

2. Turn off the firewall.

1. Return to System & Security, click [Check Firewall Status] under Windows Firewall;

2. Click [Turn on or off Windows Firewall] on the left, turn off the firewall, and click OK.

Start first - Control Panel - Security Center, and then there are Internet options below Automatic Update Firewall [Manage Security Settings at the bottom] If you want to turn it off, click on the option There will be an option to close the program, and you can turn it on from there. Very simple. - Please, please! ~~

Start - Control Panel - Security (you can see it inside after clicking on it).

I usually do this in the Control Panel, but if you have to do it in Computer Management, open the service program, find the Automatic Updates and Windows Firewall Internet Connection Sharing (ICS) services, double-click to open them, and then disable them.

Inside the control panel, both automatic updates and firewalls can be set to be turned off.

Automatic updates and network firewall recommendations are enabled. Automatically update hotfixes that can handle Windows vulnerabilities on their own to strengthen your system. And the patch is optional, you can block some of the patches you don't want, such as WGA notifications, OGA notifications, etc., etc. (that is to say, illegal authorized users are also available, just block the patches; If you are not authorized, you are better off purchasing a key to activate).

A network firewall is designed to combat cyber attacks. If you're not an enterprise user or a user with special security requirements, turn it on and leave it alone. (Windows' firewall is turned on by default).

Many people think that the firewall will be enabled by clicking "Enable" on the firewall, but in fact, it is not, it should be started - Control Panel - Performance Maintenance - Management Tools - Services - Enable Securitycenter

This will allow the firewall to be enabled.

It is recommended that you use Kaspersky.

Its antivirus and firewall features are among the best in the world.

Automatic updates are not genuine, they are all turned off.

Firewall, to put it mildly, the firewall that comes with the system is useless.

Install your own antivirus, just a firewall.

Must,For the system is its own early warning software,It won't bother you when your computer doesn't have a suspicious process.,Annoy him when there's nothing to do.,It's too late when there's something.,It's recommended to turn it on.,And you have to have a good anti-virus software.,If you want to turn it off.,Otherwise, it's recommended not to turn it off.。

And every time you turn off the system firewall, start the computer every time. A reminder will appear in the taskbar of the lower right button, saying that your system is in danger and the firewall is not turned on, and you have to turn off this prompt every time, isn't it more troublesome?

Automatic updates are recommended to be turned off, it is useless at all, it is recommended that 360 security updates be fast, good luck.

I never turn on that thing.,Running a program will pop up "whether to allow".,It's troublesome.,Automatic updates.,If you do update you're done.,Soon you'll see that you're using a pirated XP.

If you don't have a firewall installed on your machine, turn it on.

Personally, I don't think it's necessary to update automatically, 360 can help you update, and Microsoft will automatically update the patch without your knowledge, so that you will have a card that will be recommended to be turned off for no reason.

It's best if the system still has a firewall.

If your antivirus software is a security suite, then the built-in firewall, there is no need If it is not a security suite, you have to install another firewall, recommend Fengyun firewall, free, domestic.

It is not recommended that the system comes with its own, there are few functions, the firewall is mainly to manage the port and access the local program of the network, in addition, the firewall also has a monitoring registry, monitoring process, and the management of sensitive directions, and some firewalls also have the APR firewall to be used by LAN users.

Windows Update, is your system genuine or pirated? Nowadays, most people's operating systems are pirated, so there are very few people who use Windows Update, even if they are genuine users, there are many people who are troublesome with Windows Update.

Windows Update is to patch system vulnerabilities, it is recommended to use 360 security guards to patch, of course, like Super Patrol, Super Rabbit, Optimization Master, etc., all have the function of patching the system.

You don't need to open it if you install antivirus software.,Windows Update is an automatic update.,Piracy is turned off.,The genuine version is on.。

Generally, the computer system is a cracked version, or a pirated version, can not be automatically updated, once automatically updated, your computer's system is not far from being usable!! Let's close this one!!

In my personal opinion, automatic updates can be turned off, and if necessary, they can be manually updated on Microsoft's **.

And the firewall depends on your own situation, if you install a third-party firewall, Windows's own firewall can naturally be turned off, otherwise it is better not to turn it off, because the firewall in SP2 is still relatively effective.

Microsoft's firewall is useless, but it's better to leave it on than off. And his biggest feature is that it doesn't take up memory. Automatic updates are turned on, and this one can't be updated a few times a month. Anyway, it's just a matter of waiting, so you don't waste your time.

It's best to turn off the update and don't update it, so there will be a lot of viruses, and if you update it, you can use the vulnerability detection of the antivirus software to make up for it

Press Win+R and type OK to find Windows Firewall

Change the startup type to Automatic.

What kind of firewall does your computer go with? Firewall stupid and virus upgrade system, can only do to intercept intrusion into the computer attack or slow the virus, it is recommended that you or install a firewall!
