Applying network security groups (NSG) to filter traffic to and from resources, improves your network security posture. CIS Benchmarks are a comprehensive resource, RDP is one of the most attacked subsystems, Two thirds of cyber-crimes repeated within 12 months, 600 failed login attempts per hour for public RDP servers, Bluekeep – critical Windows vulnerability, Flash is dead – now delete it from your system, 100000 Zyxel firewalls have hardcoded backdoor exposed, SolarWinds hack sends chills through security industry. It is best practice not to mix application functions on the same server – thus avoiding differing security levels on the same server. Haven’t found the relevant content? 0INTRODUCTION 1. For the router you definitely need to protect it from unauthorized access. Furthermore, if your organization is subject to any corporate governance or formal security standard, such as PCI DSS, SOX, GLBA, HIPAA, NERC CIP, ISO 27K, GCSx Co Co, then device hardening will … Application Hardening. A firewall is a security-conscious router that sits between your network and the outside world and prevents Internet users from wandering into your LAN and messing around. The database software version is currently supported by the vendor or open source project, as required by the campus minimum security standards. Change default credentials and remove (or disable) default accounts – before connecting the server to the network (PCI requirement 2.1). INTRODUCTION 1. Providing various means of protection to any system known as host hardening. One of the myths is that Linux systems are secure by default. First with the workstations and laptops you need to shut down the unneeded services or programs or even uninstall them. – SNMP (Simple Network Management Protocol) v.3. It is essential that such devices are pr… According to a new report, 68% of organisations that suffered a network breach are the victim of a repeat attack within a year.  Cyber-criminals assume that organisation will not learn a lesson from the firstRead more, Bluekeep is serious vulnerability in the RDP protocol affecting Windows systems.  After months of waiting, active exploits have now been spotted in the wild for the first time, attempting to install cryptomining malware on theRead more, Recent research from Sophos highlights your public RDP server as the primary attack vector against your data centre. Ports that are left open or active subsystems that respond to network traffic will be identified in a vulnerability scan allowing you to take corrective action.  A vulnerability scan will also identify new servers when they appear on your network allowing the security team to ensure the relevant configurations standards are followed in line with your Information Security Policy. Even with a good foundation, some system hardening still needs to be done. In system hardening we try to protect it in various layers like physical level, user level, OS level, application level, host level and other sublayers. Server hardening, in its simplest definition, is the process of boosting server’s protection using viable, effective means. You should never connect a network to the Internet without installing a carefully configured firewall. Network Security is being sub- divided into two parts which are Network hardware security, which centers on Firewall Configuration Rules and secondly … » A protocol that is used to create an encrypted communications session between devices. However, there can still be some cases in which the actual traffic flowing through the NSG is a subset of the NSG rules defined. Distributed application development requires the programmer to specify the inter process communication – a daunting task for the programmer when program involves complex data structures. The aim of server hardening is to reduce the attack surface of the server. Page 7 Network hardening techniques I. – TLS (Transport Layer Security). Create configuration standards to ensure a consistent approach, How separating server roles improves security, How vulnerability scans can help server hardening. Home Infrastructure Cybersecurity Basics: Network Hardening Cybersecurity Basics: Network Hardening by Benchmark 29/04/2019 29/04/2019 Cybersecurity is an increasingly important issue for installers and integrators. Applying network security groups (NSG)to filter traffic to and from resources, improves your network security posture. 1. The vulnerability, which has become known as BlueKeep or CVE-2019-0708, remains unpatched on millionsRead more, SAD DNS is a protocol level vulnerability in the DNS system.  Microsoft has published a new security advisory which offers a mitigation to protect your DNS systems from spoofing or poisoning. The programmer should also explicitly. The attack surface is all the different points where an attacker can to attempt to access or damage the server. Active Directory domain controllers provide time synch for members of the domain, but need an accurate time source for their own clocks.  Configure NTP servers to ensure all servers (and other network devices) share the same timestamp.  It is much harder to investigate security or operational problems if the logs on each device are not synchronised to the same time. Password Protection- Most routers and wireless access points provide a remote management interface which can be accessed over the network. Device hardening is an essential discipline for any organization serious about se-curity. What does Host Hardening mean? Believe it or not, consumer network hardware needs to be patched also. 1 INTERNSHIP REPORT MTN RWANDA PO BOX 264 BY Kalimunda Hakim Student At RTUC Bachelor In Business Information Technologies _____________________ SUPERVISED BY Aymard Mbonabucya Information & Network Security Administrator _____________________.
