Before we go on to hardening, it would be wise to create a drive image using Macrium at this point to capture a clean virgin Windows install. That way, if you want to undo all the hardening in one swoop, you can reimage the machine using this image file. One of the main concepts underlying hardening is least privilege. It means to configure your system so that it is only capable of doing things you normally do, and nothing else. So, that means that if a feature in Windows is not used, it is to be turned off, or disabled. The reason behind it, is that the more features you enable, the larger your attack surface is. It means you have more to defend. The more features you have, the more potential bugs ( some security related ) you have. Now attackers know a lot about the security bugs in the system – that’s how they attack. If you go live on the internet with all features turned on, the attacker would have a lot of choices. If you disable unused features, then he’d have less to play with. One of the first things you should do in line with least privilege is to create a Standard user account, and use that account for your daily work. ![]() ![]() ![]() Let's say your laptop does not start at all.

Windows Updates has an irritating way of not working for Windows 7 or Windows 8. Here's a look at how to fix it if it doesn't work correctly like it should. Harden Windows 10 - A Security Guide gives detailed instructions on how to secure Windows 10 machines and prevent it from being compromised. We will harden the system. Go to the Italian version of this page. Can Service Pack 2 be installed on all XP installations? Ordering the service pack on a CD. Software Update Failed. The update could not be installed. Some users may see a 'Software Update Failed' dialog after restarting Firefox with the message, The update. The Cloud, Big Data, and The Future A look at how Trustworthy Computing principles will impact the future of technology. 24jul2014 Fixr : I've written a Flickr API app that includes a couple different fixes to inadequacies in Flickr. You can pick and choose which ones you want to. Only login to the administrative account to install programs, configure networking. Because when you are working in a Standard account, any malware or hacker that makes it onto your system will inherit your privilege and not have admin privileges to make system wide modifications. And. that’s a win for you. Remember that an attacker will have all the access that you have at the that moment of attack. So if you have important data stored in that account's Document folder, they will have the same access. From a different perspective, a Standard account is a barrier to other accounts, and is also a container for attacks. If you have your services set up correctly and don't allow the command Run. As, ( it is the Seondary Logon service ), then automated attacks and hackers cannot gain access to your other accounts. Control Panel, select 'View by: Small Icons'. This shows all the configurations choices available. When MS released Vista, there were some complaints about UAC asking for confirmation to do this, that and the other. So MS made a compromise in Windows 7 and allow customers to choose what level of prompting they want. ![]() Know that. turning completely off UAC also means turning off Protected Mode in Internet Explorer, and not too many people realize that a major piece of protection is now turned off. UAC pops up mostly during the setup phase, once you have finished setting up your computer, you will rarely encounter it. Control Panel\All Control Panel Items\User Accounts\Change User Account Control Settings. Windows network has 3 network types, domain, private and public. Work and home are similar and are labeled as 'private' under it's firewall tool. The private setting is set to allow 'network discovery', so that Windows is. ![]() PCs. The public setting is the most secure and is meant to be used at cafe hotspots, airports etc. If your network contains insecure PCs, then you should set the network profile to public. The domain setting cannot be chosen by the user, and is used after the PC has joined a domain. Since we are hardening the PC, we want the most secure setting, and only allow Windows to talk when it is called for. So for those that intend to join a domain, choose the private profile; and if not, choose the public profile. Some networking components implement protocols. Networking protocols are grammar rules for bits and bytes to. PCs. And each has weaknesses. So unless your environment requires that a protocol must be used, we will want to disable all except the bare essentials. More protocols mean a larger attack surface. The only protocol you really need is IPv. And most networking equipment requires IPv. IPv. 6 will be increasingly necessary as we have run out of IPv. IPv. 6 is still not very popular. If you have a IPv. Some routers do not understand IPv. ISPs don't support it either. So MS made several tunnel components that tunnels IPv. IPv. 4 to the outside. This in effect. bypasses the security offered by your NAT- router and hardware firewall. Tunnelled traffic can't be seen by IPv. Net. BIOS over TCP/IP is not required because Net. BIOS is already active without this option. Disabling Net. BIOS over TCP/IP should limit Net. BIOS traffic to the local subnet. The Discovery protocols are used to provide a nice graphical map of your network. For home users, this is not needed, as there is only one router. You would only get to see a picture depicting your PCs connected to your router. For Domain users, this feature is automatically turned off once you join the domain. File and Printer Sharing should only be enabled if you plan to share some of your folders on the network or if you want to share your locally connected printer over the network. If printer sharing is desired, it is better to get a printer that has networking built in, so that when attacked, they only gain access to a printer instead of your PC. Disable this feature unless absolutely required. In line with layers of security, besides deactivating security protocols, we will be disabling services that serve these protocols. If you have an IPv. Under the registry key “HKLM\SYSTEM\Current. Control. Set\Services\tcpip. Parameters”,right click on the right pane, create an New entry of type DWORD(3. Disabled.

Double click on that and set the value to 2. SMB is the file sharing protocol used for File and Printer Sharing and inter- process communication. MS does not recommend disabling v. Version 2 was released with Vista. Version 3 is new to Windows 8 and Server 2. There has been worms which attack SMB shares, and depending on the payload, could gain complete control of the machine. For further information on disabling all versions of SMB, read. Go to Control Panel > Programs and Features > Turn Windows Features on or off. Uncheckmark SMB 1. CIFS File Sharing Support. When you run the command 'netstat - abn', it will show you which ports are open and listening to the network. Normally, you would want to close those ports unless you really need them. Windows 1. 0's listening processes and their port numbers are RPCss ( 1. Spoolsv ( 4. 94. 10 ), schedule ( 4. That means nobody can touch those listening ports unless the firewall is off, or you have made inbound 'allow' rules to pass traffic. This has been verified by connecting to them with telnet and all attempts failed, unless one turns off the firewall or makes 'allow' rules. Also, as far as I can determine, all of those processes are essential. Windows, and they cannot be stopped without crippling the PC. Buy a router that has Stateful Packet Inspection ( SPI ) firewall. This kind of firewall will monitor outbound traffic and only allow matching return traffic. Like when you surf to a web site, your browser initiate a request to the site, and the site returns the web page. Buy one even if you have only 1 PC. And if you are using a cable modem which only has 1 Ethernet port, you definitely need one. More expensive hardware firewall routers will have more tools, like configurable rules, sending logs to remote syslog servers, and fancier protection like spotting syntactical illegal ip packets. For an example of small/medium. They have products which integrates a firewall, gateway antivirus and antispyware, and VPN. These usually costs $4. See the section Intrusion Detection part 4 below. The basic principle for configuring firewalls is 'default deny'. That means all traffic is to be blocked unless you have made a rule to allow it. Those rules are your 'whitelist' of known good applications and protocols. Window's firewall's default policy is set to inbound deny and outbound allow all. We don’t want malware to be able to call. Most people don't know that you have to turn outbound blocking on. When outbound blocking is turned on, it only allows the programs and services you specify to talk to the net. Malware will have a hard time reporting back to their. However, it is missing a feature that tells you what programs it has blocked outbound. So after installing a program that needs to connect to the net, like your antivirus program, you have test those exe files one by one to see which is responsible for talking and allow that exe to talk with a outbound rule. If you have the Automated Configuration Pack, you can right click on . This will set up all firewall rules and profile settings. How. To allow a windows service outbound: Click on Outbound Rules on the left, click on 'New Rule', select 'Custom', next to 'Services' click customize, select 'Apply to this service', scroll and find 'Windows Update', next, ports and protocol - (no change), next, IP addresses ( no change ), next, select 'Allow The Connection'. Checkmark all profiles,next. Give the rule a name, eg . Give the rule a name, eg . Select 'All Programs'. For 'Protocol Type' select 'TCP' or 'UDP' as the case.

Click 'Add' button, and in the following dialog box, type in an ip. This ip address or subnet'. Select 'Allow the connection'. Checkmark all profiles, next. Give the rule a name, eg . When you install an app, you should check the Inbound rules to see if any new rules have appeared, and disable those if you don't want inbound traffic to that app. Grand Challenges - Provide Access to Clean Water. When Samuel Taylor Coleridge wrote “water, water, everywhere, nor any drop to drink,” he did not have the 2. But allowing for poetic license, he wasn’t far from correct. Today, the availability of water for drinking and other uses is a critical problem in many areas of the world. How serious is our water challenge? Lack of clean water is responsible for more deaths in the world than war. About 1 out of every 6 people living today do not have adequate access to water, and more than double that number lack basic sanitation, for which water is needed. In some countries, half the population does not have access to safe drinking water, and hence is afflicted with poor health. By some estimates, each day nearly 5,0. It’s not that the world does not possess enough water. Globally, water is available in abundance. It is just not always located where it is needed. For example, Canada has plenty of water, far more than its people need, while the Middle East and northern Africa — to name just two of many — suffer from perpetual shortages. Even within specific countries, such as Brazil, some regions are awash in fresh water while other regions, afflicted by drought, go wanting. In many instances, political and economic barriers prevent access to water even in areas where it is otherwise available. And in some developing countries, water supplies are contaminated not only by the people discharging toxic contaminants, but also by arsenic and other naturally occurring poisonous pollutants found in groundwater aquifers. Water for drinking and personal use is only a small part of society’s total water needs — household water usually accounts for less than 5 percent of total water use. In addition to sanitation, most of the water we use is for agriculture and industry. Of course, water is also needed for ecological processes not directly related to human use. For a healthy, sustainable future for the planet, developing methods of ensuring adequate water supplies pose engineering challenges of the first magnitude. Of course, by far most of the world’s water is in the oceans, and therefore salty and not usable for most purposes without desalination. About 3 percent of the planet’s water is fresh, but most of that is in the form of snow or ice. Water contained in many groundwater aquifers was mostly deposited in earlier, wetter times, and the rate of use from some aquifers today exceeds the rate of their replenishment.“Overcoming the crisis in water and sanitation is one of the greatest human development challenges of the early 2. U. N. To meet current needs, which increasingly include environmental and ecosystem preservation and enhancement demands, the methods will have to become more sophisticated. One large- scale approach used in the U. S., China, India, and other countries has been to divert the flow of water from regions where it is plentiful to where it is scarce. Such diversion projects provide some short- term relief for cities, but do not appear practical as widespread, long- term, ecologically sound solutions, and this method generally will not be able to meet agricultural needs. Furthermore, diverting water to some people often means less for others and can become an explosive political issue. What is desalination? Desalination is extracting the salt from seawater. Desalination is not a new idea and is already used in many regions, particularly in the Middle East. Saudi Arabia alone accounts for about a tenth of global desalination. Israel uses desalination technology to provide about a fourth of its domestic water needs. Modern desalination plants employ a method called reverse osmosis, which uses a membrane to separate the salt. More than 1. 2,0. But desalination plants are expensive to build and require lots of energy to operate, making desalination suitable mainly for seaside cities in rich countries. It therefore has limited value for impoverished countries, where water supply problems are most serious. New technologies that would lower energy use — and therefore costs — might help desalination’s contribution. One potentially useful new approach, called nano- osmosis, would filter out salt with the use of tiny tubes of carbon. Experiments have shown that such tubes, called nanotubes because their size is on the scale of nanometers, have exceptional filtering abilities. Even with such advances, though, it seems unlikely that desalination alone will be able to solve the world’s water problems. Other approaches will be needed. What other technologies will provide clean water? Technologies are being developed, for instance, to improve recycling of wastewater and sewage treatment so that water can be used for nonpersonal uses such as irrigation or industrial purposes. Recycled water could even resupply aquifers. But very effective purification methods and rigorous safeguards are necessary to preserve the safety of recycled water. Agricultural irrigation consumes enormous quantities of water; in developing countries, irrigation often exceeds 8. Improved technologies to more efficiently provide crops with water, such as “drip irrigation,” can substantially reduce agricultural water demand. Already some countries, such as Jordan, have reduced water use substantially with drip technology, but it is not a perfect solution for plant growth (e. Water loss in urban supply systems is also a significant problem. Yet another strategy for improving water availability and safety would be small decentralized distillation units, an especially attractive approach in places where infrastructure and distribution problems are severe. One of the main issues is economical distribution of water to rural and low- income areas. Some current projects are striving to produce inexpensive distillation units that can remove contaminants from any water source. A unit smaller than a dishwasher could provide daily clean water for 1. Such approaches will help to address the very real problem of inequitable distribution of water resources. Even within a given country, clean, cheap water may be available to the rich while the poor have to seek out supplies, at higher costs, from intermediary providers or unsafe natural sources. Technological solutions to the world’s water problems must be implemented within systems that recognize and address these inequities. References. Gleick, P. H., et al. Chicago: Island Press.
