  • Magic Quadrant for Secure Web Gateways
    15/11/2019 Gartner Reprint Licensed for Distribution Magic Quadrant for Secure Web Gateways Published 11 November 2019 - ID G00380121 - 35 min read By Analysts Lawrence Orans, John Watts, Peter Firstbrook Rapid growth of cloud-based secure web gateway services has become a disruptive force in the market. SWG vendors are adding cloud access security broker, remote browser isolation, firewall and other advanced features to enhance the security of their platforms. Market Definition/Description The rapid adoption of SaaS applications such as Microsoft Office 365, Salesforce and others is driving enterprises to adopt cloud-based secure web gateway (SWG) services. Enterprises are rearchitecting their WANs so that web traffic from remote offices flows directly to the internet (via local internet breakout connections), instead of backhauling it over expensive MPLS links to a centralized data center. As part of this rearchitecture, enterprises are utilizing cloud-based security stacks, so that web traffic from remote offices first flows through a cloud security service (mostly SWG services) before it reaches its final internet destination. A secondary driver for the adoption of these cloud services is the need to protect mobile laptops when they are off the corporate network. We continue to see interest from enterprises seeking to integrate cloud access security broker (CASB) and SWG functionality. SWG vendors are responding to this trend, by either acquiring CASB technology or partnering with CASB providers (mainly Microsoft and its Cloud App Security service) to deliver more tightly integrated CASB and SWG solutions. CASB vendor Netskope is also addressing this trend, as it continues the development of its SWG solution introduced in 2018.

The aim of the paper is to analyze mobile application developers’ possibilities for syncing content using major free cloud storage providers. The paper describes the cloud computing in mobile context and highlights cloud providers APIs. Experimental results are analyzed in order to identify the best cloud storage solution for syncing mobile applications, depending on the operating system on which they are implemented.

Cloud computing technology is vulnerable to number of security threats and attacks. Security challenges are major barriers in the adaptation of cloud computing model. Security issues are related to virtualization, network and data including eavesdropping, masquerading, privacy, confidentiality, availability of resources, access control, and identity management. In cloud computing, data are stored on a remote server and accessed through public network. Many of the cryptographic based solutions such as encryption/decryption and digital signature for authentication have been developed. In this paper, we have identified and discussed number of security issues such as authentication, access control, data confidentiality, data integrity, identity management, legal and contractual issues, data breaches, data theft, and unavailability. Moreover, we have also discussed some possible solutions to the security issues and their feasibility and security analysis in real time cloud environment.

I. Omotosho* *Corresponding Author: O. I. Omotosho. Email: [email protected] Department of Computer Science and Engineering, Ladoke Akintola University of Technology, Ogbomoso, Oyo state, Nigeria Email: [email protected] I. INTRODUCTION Cloud computing is commonly used to represent any work done on a computer, mobile or any device, where the data and possibly the application being used do not reside on the device but rather on an unspecified device elsewhere on the Internet. The basic premise of cloud computing is that consumers (individuals, industry, government, academia and so on) pay for IT services from cloud service providers (CSP). Services offered in cloud computing are generally based on three standard models (Infrastructure-as s service, Platform-as a service, and Software as a Service) defined by the National Institute of Standards and Technology (NIST). The reason for cloud existence is to resolve managing problems being faced for data that were excessively stored, either mandatory capacity was limited due to the infrastructure of the business, or large capacity that led to a wasted capital. Apart from those major factors such as the initial capital, capitals and the service-fix cost, the sophisticated effort for the patching, the managing and the upgrading of the internal infrastructure is a huge obstacle for firm‘s development and mobility.

CYBER SECURITY STATISTICS Official statistics from HMG 2020 identified that almost half of businesses (46%) reported having a security breach in the past 12 months. Of these 46% of businesses, more are now experiencing regular issues at least once a week (32% in 2020 compared to 22% in 2017). The nature of incidents that organisations are now facing are in 2 main categories; phishing attacks (72%) and viruses or other malware (33%). Of the 46% of businesses that have identified a breach or attack, 1 in 5 (19%) have experienced a material outcome, losing money or data. Losing data does not only impact your business' reputation, but it can also lead to fines. Under GDPR, a less severe infringement could result in a fine of up to £10 million or 2% of annual revenue. A more severe infringement could result in a fine of up to £20 million or 4% of annual revenue (whichever amount is higher).

  • May 25, 2021 TLP: White Report: 202105251512 Overview of Conti Ransomware
    HC3: Analyst Note May 25, 2021 TLP: White Report: 202105251512 Overview of Conti Ransomware Executive Summary Conti ransomware has recently been brought back into the spotlight due to its attack on Ireland’s national health system - the Health Service Executive (HSE). Conti leverages many of the tools and techniques common among major ransomware operators such as encryption, double-extortion via the use of a leak site, ransomware-as-a- service partnerships and many of the frequently-successful infection vectors such as phishing and remote desktop protocol (RDP) compromise, among others. One of several recommendations given by Sophos security researchers to protect networks from Conti is to keep regular backups of important and current data on an offline storage device. Report On May 14, 2021, Ireland’s HSE shut down “all national and local IT systems” in response to a Conti ransomware attack detected on their networks. The shutdown was an effort to contain the ransomware and “to protect [the systems] from encryption by attackers.” Additionally, all HSE employees were instructed to turn off their computers and not turn on computers that were already powered down. Conti ransomware is ransomware-as-a-service malware that targets victims primarily in North America and Western Europe. According to Sophos, the industries most frequently targeted by Conti are retail, manufacturing, construction, and the public sector but, any sector/industry can be targeted. Conti was found to have one of the biggest market shares of all ransomware operators in the first quarter of 2021 by Coveware. Conti is generally considered a successor to the Ryuk ransomware; however, one significant distinction between the two malwares is Conti ransomware uses the double-extortion technique.
