Linux networking commands, network monitoring tools, configuration examples and administration are covered in this tutorial. The YoLinux portal covers topics from desktop to servers and from developers to users. By: Kyle Snow and Peter Pizzolongo. In late January 2014, researchers at the University of Virginia released a working paper with the provocative title “Is Kindergarten the New First Grade?' The paper amplifies concerns.
Panda Internet Security 2. Review. Panda Internet Security 2. It offers support for Windows, Mac, Android and i. OS devices. Internet Security is part of a lineup for AV solutions from developer Panda Security, where each tool comes bundled with more features than the last. Differences between the four Panda editions.

The new look of Panda Internet Security 2. Windows 1. 0Scanner and scan settings. In the main window, you can check out total scanned files, items in the quarantine, and blocked threats. There are three scan modes available: full mode for all hard disks, quick mode for critical areas, and custom mode. Any of them can be scheduled to run daily, weekly or monthly. During the scanner, you can pause the job or schedule the PC to shut down on task completion.

On threat detection, Panda either sends the items to the quarantine or removes them from the HDD. In the quarantine, you can find out the item's original location and look up descriptions of threats on the developer's website, in order to decide whether you want to permanently remove the files or restore them to the disk. When it comes to the real- time guard settings (i. Plus, you can empty the quarantine automatically (every three days, week or month), exclude any files, folders or file extensions, as well as delete files restored from the quarantine (these are auto- excluded from future scans if you restore them to the disk). Firewall with program control and intrusion prevention. The Panda firewall protects the computer from network- based intrusions (such as UDP floods), blocks processes, and monitors connections and shared resources between your PC and others in LAN. It can be configured for home, work or public places, and it handles events silently, without displaying any notifications.
It has a list of predefined processes that it filters inbound and outbound connections for, in addition to another list of rules recommended by the developers (e. Rules can be exported to file to import them later. As far as intrusion prevention is concerned, you can either stick to the default configuration or disable some features: IP explicit path, land attack, SYN flood, TCP port scan and flag check, IP and TCP header length check, UDP flood and port scan, Smart ARP, OS detection, ICMP Drop unsolicited responses, Small PMTU, Smurf, fragmentation control. The ones you can enable are Smart DNS and DHCP, and ICMP no echo requests.
Process monitor and USB protection. The process monitor shows the processes of currently running applications, along with the total executed processes, those accessing the Internet, blocked ones, and those of medium or high threat level. You can find out their classification level (secure or insecure), number of HTTP connections established, and date of discovery.
The USB protection component monitors your machine's USB ports, identifies all new devices, and prevents them from running the autoplay feature, which is a popular virus infection method (like the Conficker worm). It works not only for USB removable drives but also for CDs and DVDs. Panda shows a systray notification on new device detection and offers to scan it. Furthermore, it can permanently disable the autorun. Panda can auto- perform this action for every USB drive inserted in the PC. Plus, you can disable scan suggestions or disable the whole USB protection module.
Wi- Fi protection and rescue kit. The Wi- Fi protection feature oversees your Internet connections and lists all remote devices connected to the same network as you. This way, you can find out if unauthorized users have decrypted your wireless password and are connected to your network. It also shows which devices are linked to which network. It's possible to find out the remote device's IP and MAC address, manufacturer and timestamp, in addition to the router address, encryption type, authentication mode, and signal. You can disable notifications when connecting to networks with security issues, ask the program to report only networks with low security, exclude any networks from notifications, or deny PC access to any linked device. The rescue kit is capable of creating a rescue USB drive that can be used to boot infected computers.
It can also download, install and run Panda Cloud Cleaner to find and remove malware. Parental control. The parental control module enables parents, teachers and employees to set restrictions to others using the current computer when surfing the web.
Only administrators have access to this feature, and they can configure settings for the current administrative account or other PC users. Panda has a few predefined filters in this regard and gives you the possibility of browsing a long list of content types to deny access to: advertisements and popups, alcohol and tobacco, anonymizers, chat, forums and newsgroups, criminal activity, and so on. Moreover, you can deny access to all webpages classified as unknown (which are not part of the list), as well as create two lists of addresses and domains to always allow and deny access to. Panda Internet Security 2.
View parental control statistics. The effects are immediately applied to all your web browsers, and Panda shows a notification with the blocked page and reason. Since this module is only applicable to the current computer, don't forget to set a password to the Panda Internet Security console if you're setting restrictions to the administrative account. In the console, you can check out various statistics collected by the application, namely the most visited websites and categories, along with the denied websites and categories. This information can be filtered for each PC user and for the current day, week or month. Data shield and application control.
Data shield is a security feature that protects specific data from programs attempting to access it, and lets you manage permissions for specific applications. It defends the Documents folder along with Office documents, images, audio and video files by default. However, you can remove folders from the list and add custom ones, as well as edit the file extensions identified by each group or create new groups with custom file formats to protect. Likewise, you can remove the default programs from the list, change their permission, or add new ones by indicating their launch file and permission: allow or deny access when attempting to access the protected data. It shows a systray message every time an unknown program (any unlisted app) tries to access the protected folders and asks you what to do. Information about last access attempts can be inspected in the AV console, namely the name, full path, date and time for each blocked process.
You can forbid access to safe applications anytime, or instruct Panda to deny access to all unknown programs without user confirmation. The application control component may look the same as the previously described programs list. The difference is that, in the data shield, you can set permissions to processes only when they try to access the protected folders you indicate, while application control enables you to allow or deny access to programs when they try to run. Just like before, Panda automatically blocks tools with . The AV console shows the recorded URLs, reason and date, total blocked links, malware, phishing and fraud, along with URLs allowed by the user.
As far as settings are concerned, you can create a list with allowed addresses and domains. The virtual keyboard enables you to securely type email accounts, user names and passwords on social networking or banking websites, for example, in case anyone installed a keylogger on your computer. As far as general settings go, you can log in with your Panda account, set a password for accessing the AV console, check for updates (these are performed automatically), disable notifications when playing a game or working with another app in full screen, change proxy settings, generate an advanced report, and hide the Panda news notification. All important events, such as scan, firewall, wireless network and data shield activity, are recorded to reports, which can be printed or exported to file. Testing the malware detection ratio and scan speed. We tested Panda's malware detection ratio and scan time on an Intel Core i. S CPU @ 2. 9. 0hz with 8.

Pro 6. 4- bit. The target was a 2. GB folder filled with 8,5. Unfortunately, the real- time guard was completely unresponsive during our tests.
It didn't react when we extracted the files from the password- protected archive, opening their folder, selecting them, or running them. We asked Panda to run a custom scan with default settings on the 2.
GB folder. The task took the mind- bending time of 8 hours to finish, after which the AV identified and quarantined 6,2. We ran three more scans after this, and Panda found and quarantined a few more files with each scan. In the end, it left behind 1,9. CPU and RAM consumption was barely noticeable during this time.
In the following stage our of evaluation, we retested the scan time. A critical area scan on the 1. GB SSD took 4 minutes, while a custom scan on the Windows directory (2. GB) took 2. 0 minutes. The Good. It's available for Windows, Mac, Android and i. OS devices. The interface blends well with the Windows 1.
Any module can be disabled and tiles can be removed from the console.
