Physical layer security (PLS) which protects data secrecy based on information-theoretic techniques, has lately received significant academic interest. The growth of wireless communications to 5G and beyond presents new difficulties for physical layer security research. As the existing Radio-Frequency (RF) networks cannot meet the ever-increasing data rate demand, optical wireless communication (OWC) based on free-space optical (FSO) techniques, has been proposed as a promising technology to overcome the RF spectrum limitations. Compared to RF networks, the FSO networks are more secure and less vulnerable to eavesdropping because of the small coverage provided by the narrow optical beam, and because they work properly only in the presence of the line-of-sight components. However, the secrecy performance of FSO networks may be compromised by the presence of an adversarial eavesdropper. This paper reviews all the conducted work on physical layer security in the free space optical networks. Furthermore, the paper proposes several open problems in these networks to optimize and enhance security performance
