The Internet of Things (IoT) Cybersecurity and Privacy Risks The IoT ecosystem poses cybersecurity and privacy risks that extend beyond traditional data security. To address IoT-specific cybersecurity and privacy risks – including those posed by cyber, physical, and human elements. This article provides an overview of the IoT cybersecurity and privacy risks. How the introduction of IoT to networks and infrastructure has changed the cybersecurity and privacy risks organizations are facing,and how managing these cybersecurity and privacy risks has become increasingly difficult for IT security departments.
Public Web servers often support a range of technologies for identifying and authenticating users with differing privileges for accessing information. Some of these technologies are based on cryptographic functions that can provide an encrypted channel between a Web browser client and a Web server that supports encryption. Without user authentication, organizations will not be able to restrict access to specific information to authorized users. All information that resides on a public Web server will then be accessible by anyone with access to the server.
Securing the Web Server Operating System Protecting a Web server from compromise involves hardening the underlying Operating System (OS), the Web server application, and the network to prevent malicious entities from directly attacking the Web server. The first step in securing a Web server is hardening the underlying OS. All commonly available Web servers operate on a general-purpose OS. Many security issues can be avoided if the OSs underlying the Web servers are configured appropriately.
Businesses Are Using Cloud Apps What are cloud apps? In general, cloud apps are the concept of remotely hosted software and services, provided by a supplier. These suppliers are called cloud providers. Typical cloud apps offered by cloud providers include email, calendar, documents, online storage, sales, customer service, and more. Some of today’s many cloud providers are well known names in industry and include companies such as Amazon, Google, 37signals, Intuit, Microsoft, and Box.
Intrusion Detection and Prevention System Principles Intrusion detection is the process of monitoring the events occurring in a computer system or network and analyzing them for signs of possible incidents, which are violations or imminent threats of violation of computer security policies, acceptable use policies, or standard security practices. Incidents have many causes, such as malware (e.g., worms, viruses), attackers gaining unauthorized access to systems from the Internet, and authorized users of systems who misuse their privileges or attempt to gain additional privileges for which they are not authorized.
Is My Business Too Small to Worry About Cybersecurity? Many businesses have been putting resources including people, technology, and budgets into protecting themselves from information security and cybersecurity threats. As a result, they have become a more difficult target for malicious attacks from hackers and cyber criminals. Consequently, hackers and cyber criminals are now successfully focusing more of their unwanted attention on less secure businesses. Because small businesses typically don’t have the resources to invest in information security the way larger businesses can, many cyber criminals view them as soft targets.
Ransomware is the fastest growing malware threat, targeting users of all types, from the home user to the corporate network. On average, more than 4,000 ransomware attacks have occurred daily since January 1, 2016. This is a 300-percent increase over the approximately 1,000 attacks per day seen in 2015. There are very effective prevention and response actions that can significantly mitigate the risk posed to your organization. Ransomware targets home users, businesses, and government networks and can lead to temporary or permanent loss of sensitive or proprietary information, disruption to regular operations, financial losses incurred to restore systems and files, and potential harm to an organization’s reputation.
Ransomware is a type of malicious software cyber actors use to deny access to systems or data. The malicious cyber actor holds systems or data hostage until the ransom is paid. After the initial infection, the ransomware attempts to spread to shared storage drives and other accessible systems. If the demands are not met, the system or encrypted data remains unavailable, or data may be deleted. How Do I Protect My Business From Ransomware?
Every community organization, corporation, business, or government agency relies on an outward-facing website to provide information about themselves, announce an event,or sell a product or service. Consequently, public facing websites are often the most targeted attack vectors for malicious activity. Web server attacks include: Exploitation of software bugs in the web server Denial of Service (DoS) or Distributed Denial of Service (DDoS) attacks Compromising “backend” data through command injection attacks, such as Structured Query Language (SQL) injection; Lightweight Directory Access Protocol (LDAP) injection; and cross-site scripting (XSS) Website defacement for malicious purposes Using compromised web server capabilities to attack external entities Using a compromised web server to distribute malware.
The World Wide Web is one of the most important ways for an organization to publish information, interact with Internet users, and establish an e-commerce/e-government presence. However, if an organization is not rigorous in configuring and operating its public Web site, it may be vulnerable to a variety of security threats. Although the threats in cyberspace remain largely the same as in the physical world (e.g., fraud, theft, vandalism, and terrorism), they are far more dangerous as a result of three important developments: increased efficiency, action at a distance, and rapid technique propagation.
