You have learned a number of operating system features that are used to secure systems, such as authentication and authorization Authentication is the process by which a user presents logon credentials that are then veri ed by the network server against a database; if the credentials are correct, the user is allowed to access the network After a user has been authenticated, an access token is generated that is used to authorize the user to access various network resources A network resource uses an access control list to determine who is allowed access A rewall is a device used for protecting one network from a second interconnected network, such as the Internet Firewalls compare the data passing through them with rules set up to allow or deny access There are several architectures for rewalls; three of them are dual-homed host, screened host, and screened subnet A dual-homed host rewall has two network interfaces and acts as a gateway between the two networks A screened-host rewall has a screening router placed between the public network and the dual-homed host rewall This provides an additional level of security against outside intrusion A screened subnet rewall, meanwhile, puts a screening router on both sides of the rewall host This provides protection on both sides of the host Three rewall types are in use: packet-level rewall, application-level rewall, and circuit-level rewall The packet-level rewall controls data at the network and transport layers The type that works at the application level acts as a proxy and controls the top three layers of the OSI model A circuit-level rewall works like an application-level rewall but operates at the transport layer Additional security features have been added to rewalls to provide better service, such as support for VPNs and caching and better management tools Proxy servers can also function as rewalls and can be used to enhance Internet access as well as function as rewalls by ltering ports Data security has become increasingly important as networks are becoming interconnected Data encryption provides a way to ensure that the data is kept secure Encryption is the process of taking plain text data and converting it into a format that is unreadable A key is used to encrypt the data and then to return the data to a readable format Two types of encryption are in use: symmetric and asymmetric (public-key/private-key) Two common encryption methods include stream cipher and block cipher Two standards for encryption have been accepted: the Digital Encryption Standard (DES) and RSA Both use different methodologies and are in wide use today Digital signatures can be used to verify that a message arrived without being tampered with Digital signatures do not encrypt a message Instead, they attach a signature that can be veri ed against a certi cate authority Windows 2000/ XP/2003 use certi cates to encrypt les on an NTFS volume.
