How To Turn On The Firewall On Mac
Mac firewall settings can be found in the Security and Privacy preference in System Preferences. To enable Firewall in macOS and OS X v10.6 or later:
The native Mac firewall is designed to prevent unauthorized applications, programs, and services from accepting incoming connections. Thus, if you want an advanced firewall that also scans outgoing packets, you will need to use a more sophisticated firewall such as Little Snitch.
Fix : Check For Malware
The Your connection is not secure message can appear when there is a malicious program on your PC that changes the system settings and causes malfunctions. Use Auslogics Anti-Malware to fix this problem. It checks for malware and data safety threats and gets rid of them. The tool does not conflict with the main anti-virus on your PC.

Check That Your Firewall Is Functioning Correctly
Your computer’s firewall is your first line of defense against threats on the internet. It is a vital network security system that constantly monitors and controls incoming network traffic based on pre-defined rules.
Advanced firewalls also monitor outgoing traffic to block potentially malicious traffic. This allows the firewall to prevent malware exploits such as Trojans from communicating with Command and Control servers either to steal your data or infect you with secondary payloads.
A firewall secures against vulnerabilities by constantly monitoring all your ports for incoming and outgoing packets.
A firewall also protects against hackers who use port scanning tools to scan the internet for computers with open ports that could be vulnerable . If, for example, you have installed a program that opens the FTP port, hackers could attack you via that port.
Both macOS and Windows computers come with a native firewall. This means that all you need to do is tell your Operating System whether you are using a public or private internet connection, and it will do everything else for you.
You only need to alter the firewall settings if something conflicts or you need to whitelist a program from the perimeter created by the firewall’s default settings.

Consider Changing Your Routers Ip Address
Default router IP addresses are easy for hackers to find. Sometimes they can even be found online. For extra protection from router attacks, you can change your routers address.
Log into your router admin console and search for network settings or LAN/DHCP. Change your IP address and save. Note the new address.
It should be sufficient simply to substitute a couple of numbers. Once changed, you use the new address to access your router settings. If for any reason, you need to change your IP address back again, you can restore your router to its factory settings.

Why Ip Addresses Matter
VPNs also grant you a new IP address. This not only safeguards your anonymity, but also widens the amount of content you can access. Think of your IP address as being like a physical address in the real world it tells internet servers where to send information and content you request. But because a VPN provides you with a new IP address, sites you access only know the IP of the VPN, and not the one tied to your computer.
Also, many content providers like Netflix and BBC iPlayer use IP addresses as a way to figure out whether or not to allow you to access content that is limited to a particular region. By using a VPN server in a different country, you can get a foreign IP address, unlocking tons of media you might not otherwise have access to.
How To Test Your Firewall
Once you have assured that your Firewall is switched on, you can test it to make sure it is working. The good news is that you don’t need to hire a penetration tester to do this because there are services designed to probe your Firewall for vulnerabilities automatically.
ShieldsUP from the Gibson Research Corporation is a useful service that anybody can use to check the integrity of their computer’s firewall for common vulnerabilities and open ports.
If you have never tested your computer before, the service recommends that you start by using the File Sharing and Common Ports buttons.
There are four tests available on the website:
Messenger Spam test. This sends you a test Microsoft Windows Messenger message to see if you are potentially vulnerable to attacks carried out by spammers using these types of messages.

S To Stronger Wifi Security
With the continuous proliferation of public hotspots, and increase in a remote workforce, more and more attention has been drawn to the security measures in place to prevent wireless man-in-the-middle attacks. You should start by using TLS/SSL Certificates to provide network security. However, in addition to employing TLS Certificates to provide network security, these WiFi security options will dramatically improve the security of your network.
1. Use Sophisticated Passwords
Like all passwords, the WPA2 password that you use to secure your wireless network should be long and sophisticated enough to foil hackers attempting to aircrack your password. Avoid personal names, simple dictionary words, or easily guessed numbers should be avoided.
2. Change the Default WiFi Admin Username and Password
The easy first step to improved security is to change the default username and password. Since most routers dont require a physical connection to log into the admin interface, eliminating this vulnerability removes the lowest hanging fruit available to hackers.
3. Use the Latest WiFi Encryption
4. Encrypt WiFi Router Admin Pages
5. Update the WiFi Router Firmware Frequently
6. Consider Locking Down MAC Addresses
7. Train Users Not to Auto-Connect
8. Use Always-On SSL
Fix : Bypass The Warning
When faced with the Your connection is not secure message while attempting to visit a trusted website, simply bypass the warning. Heres how:
- On the error page, click on Advanced.
- Click on Add Exception.
- Now click on Confirm Security Exception.

Use A Guest Network Wi
Keeping your main Wi-Fi connection private and accessible only to permanent residents of the house is a good way to stave off cyberattacks. Dont give your credentials to anyone, be them neighbors or close friends. You never know with whom and under what circumstances they share your login details.
And even if they dont do that, they might still connect to your network with an infected device when they visit. This can and probably will infect all your connected devices. Having a separate network limits the risk of the threat spreading to every single machine linked to your Wi-Fi.
When setting up your visitor network, make sure to create a different password than you have on your main Wi-Fi, for obvious reasons. After all, you dont want to go through all this trouble of having a secondary connection, just to have it all be in vain because its credentials were the same as for your primary one.
Enter Your Ssid And Password
SSID is considered the networks name for those unaware, and a passphrase or password will be required by every device you want to connect to the network.
While choosing a strong password, take care of a few things:
- It should contain symbols, letters, and numbers.
- To avoid any brute force attack from the hackers, keep the password complicated.
- If you are unable to decide on a secure passphrase, take help from an online password generator.

Keys To Keeping Your Home Wi
Many people buy a wireless router, bring it home, plug it in, connect it and then forget about their Wi-Fi network.
When you fail to secure your wireless network, not only can someone use your network for illegal or malicious activities, they can also steal user names, passwords, bank account information, social security numbers and other personal information you have stored on your computers and devices.
Change The Network Name
As explained in the previous section, router manufacturers produce the same settings for every item of a product line that they produce. Often, a manufacturer will install the exact same administration software on all of its router models. That consistency makes life easy for hackers.
Free network detection software lets hackers see all the surrounding wifi networks. The hacker doesnt need to know which home the signal comes from because he doesnt need to break into your house in order to get into your network. Each network is identified by a name, called an SSID.
Router manufacturers often put the brand name or model of the router in the SSID. If you got a router from your internet service provider, the ISP might change that SSID when to show their own name instead of the manufacturer. If you bought the router yourself, its SSID will probably identify the manufacturer or even the model of the router.
A hacker can use the information that appears in the SSID to look up the default username and password for the router with little effort. Change the SSID so that it doesnt give away the router brand or model. Dont choose an identifier that includes your name, address, or telephone number. Dont use any other personal information in the name. So, 10BullLane,JBDecker Network, and Homenet-12281975 are all bad ideas. Avoid making political statements, dont use offensive language, and dont provoke hackers with challenges in your SSID. Just make it bland.

How A Vpn Works
When you access the internet without a VPN, your computer connection is basically naked, as it were. Your Internet Service Provider can see what content you access. That includes streaming sites, torrents, and games. But when you connect to a VPN, the VPN server acts as an intermediary between your computer and the web.
To put it simply: you send a request to the VPN, the VPN sends a request to the server where the content is hosted, and then the process runs in reverse. However, because the VPN is between you and the content, your ISP will only see you accessing the VPN. Thus, it wont see your internet activity. Besides acting as an intermediary, VPNs protect you in two other key ways: they encrypt your internet traffic and grant you a new IP address .
Keep The Router Firmware Up To Date
The router manufacturer should update the firmware on your gateway automatically. However, just as you should make a monthly schedule to change the wifi password, you should also regularly check for updates. The router console should include this option. If not, make it a habit on the first of the month to check the router manufacturers website for any updates and install them if they are available.
Another trigger for firmware updates should be any news stories that speak about major virus attacks. Usually, new viruses spread because a hacker discovered a security weakness, called an exploit. Hackers sometimes detect these weaknesses before the technology companies. The outbreak of a serious attack will provoke the router producer to check through its firmware code to make sure its equipment is not vulnerable to the new attack. If it is, they will issue a security patch. So, check on the website of your routers manufacturer whenever these news stories break.

Change Your Ssid & Wifi Access Password Periodically
SSID is the name of your WiFi connection. WiFi routers are provided default SSIDs according to brand and model. However, certain brands and models have known vulnerabilities.
An intruder can use the default SSID to identify the router and then exploit it using its known vulnerabilities. But you can mitigate this threat by assigning a unique SSID to hide what type of router it is.
Closely related to SSIDs are WiFi access passwords. In order for any user to gain access to a routers wireless connection, that user will need to know both your routers SSID and its corresponding password. As some routers have known default passwords , assigning a new password will prevent an intruder gaining unauthorized access.
No network is completely safe though. Determined intruders will find ways of obtaining your password through a variety of methods. But these methods usually take time, patience, and creativity.
